Oh. I dont want to be a teacher. He was studying at the i. O. C. Not a Teacher Training College in the mexican state of get a little. But one bullet changed everything. This footage shows the fateful moment. Ill go and around 50 other students had commandeered public buses to get back to the college after a demonstration such actions arent unusual in parts of mexico. Suddenly police stop the bus and then open fire on the armed students hit by a bullet although fell to the ground. 6 students were shot dead 2 more were seriously wounded. 43 students all the aged between 18 and 23 were abducted theyve never been seen since just like thousands of others in mexico. A number of Police Officers were subsequently arrested accused of carrying out the murders a number of the weapons used in those crimes were German Military grade 36 Assault Rifles made by a heckler and koch. But the German Government hadnt approved their export to this region so how did they get there. A court in the city of took up the case the almost year long trial was germanys most detailed investigation of an arms deal to date. The verdict surprised many. The case was initially brought so you can crush a prominent opponent of germanys arms industry the managers and walked away free thats the big scandals in proof of it too close judicial system so where the managers of heckler and koch not responsible for the illegal weapons deal in the up. And you know the court. Now but so was the conviction in this chamber that there was insufficient evidence to suggest the other defendants to pass in the crimes i. Think that. Were. So what actually happened it all began in 2005 german arms manufacturer heckler and koch wanted to export thousands of g 36. 00 Assault Rifles to mexico along with submachine guns so the company submitted an application to the German Economics Ministry in berlin but the Foreign Ministry expressed concern citing Human Rights Violations by Mexican Security forces including abductions and murder and get away at all and other states. The Economics Ministry sought a compromise. Meanwhile heckler and koch was waiting impatiently for permission to export as the companys then Sales Representative from mexico explains. We can only identify him as marcus b. And then come to be deformed philokalia or really with and asked by sounds whether we could change the designated and use a difficult because someone in history had requested that certain aspects shouldnt be mentioned and. Techno and call had originally presented this and you certificate from the Mexican Defense ministry to the German Economics Ministry. The details of the certificate showed clearly that the weapons were partly intended for mexican states considered particularly dangerous. They form so i wrote an email to my wife from the computer. Asking or to ask the head of de camp the official body responsible for arms sales in mexico whether it was possible not to name these 3 states and to issue a new and use so once the Economics Ministry had informed tecla and call which mexican states would not be approved the company submitted a new end you certificate where the critical states were no longer mentioned but the strange thing was the exact same number of guns would still be supplied to mexico which surely should have been noticed. But approval for the export was given and the deal began. Over the following years a team from heckler and koch travelled all over mexico showing Police Officers in the army how to use the firearms. Here they arent colima but they also went to the states that were supposedly banned including get a table where the weapons would soon be used. On 19 year old jihadist solano for example. This was him dancing at his brothers wedding just days before Security Forces would destroy his life forever. It was a clever child really bright he was always keen to see everything and to learn thats why he went to college now last call. Details of that night haunt the family. Of those brother lay on their tells us what happened. In the middle but wolf. I only there were a number of pastors who was in the 1st one you tomorrow or was it when the attack started they were already heading back to the college in was the 1st the police started pursuing them then a Police Vehicle not long after the junction i had to stop them leaving the city. In this about the yeah so the students got out of the bus although it was one of the 1st to get out he wanted to talk to the police who were blocking the road in the hope that they could proceed or not the police immediately started shooting but i dont have. The other students got off the buses and started filming with their cell phones when aldo was hit by a bullet or the other scream for help. They called an ambulance for their friend while running for cover themselves more shots fell. That same night all those family rushed to the hospital in one day you know i saw him and he had a bullet wound to his head the bullet went in here and came out here. Drug cartels kill thousands in mexico every year but the Security Forces are also responsible for many deaths. One of the heckler and koch gun instructors started to have doubts. In 2010 he testified to state prosecutors against his former employer heckler and koch. It was a damning indictment of colleagues and managers. That led to 2 police raids on the Company Premises and a mammoth investigation. Or and these is it took an 8 long years from the start of the investigation to the trial my opening in my 2080 or so i think i think the world. In 2018 the largest trial of its kind in german postwar history finally got underway. Trial observers took detailed minutes. Jaan fun aachen was one of them. He was previously a weapons inspector for the United Nations and a member of the german parliament. I remember 3 things from the 1st day firstly the charges were read out which included conspiring to commit crimes the 2nd was that the 2 main suspects werent in the room and one has since done it the other was half the cox mexico representative who lives in mexico and was allegedly not well enough to travel. So his trial was separated off. With. The defendants included ex c. E. O. Peter biola and another former heckler and koch c. E. O. To past employees from the marketing division. The company heckler and koch itself as a codefendant and a secretary from the export department but through the other thing i remember was the initial statements given by the accused where it was totally clear they had no sense of guilt and i think they were really serious about that. The argument was they had received approval for exports to mexico and it was so they exported to mexico pretty cool they couldnt work out why they were in court that. The end you certificate is the centerpiece of germanys arms control mechanism in this document the buyer declares where the weapons will be delivered and where they will be used ruling out that they will end up anywhere else several different ministries examine the application under the direction of the Economics Ministry. The governments export control office then takes care of the licensing procedure. Noida bought it off was president obama for 10 years. Hes well acquainted with the procedures and knows those who worked in the Economics Ministry during the period in question. It they thought of the head that id call a good as the in the head and cock case the colleague involved at the Economics Ministry was not someone who exercised any particularly critical judgment in that regard. Shall we say to the point that. That official who was in a senior position in the Economics Ministry was one of the 1st witnesses to be called his testimony got off to an uncomfortable start. Thats why youre looking for art form for the witness was asked by the presiding judge to disclose what the mexico deal was all about he answered one moment and put a huge briefcase on the table guns he pulled out an entire file therefore there was mounted and the judge asked him what he was doing he said i need to find on the investigation to get the indictment they are going to start and watch out arent there going to you can see the faces of the state prosecutors turning red because thats not a lot of its me as i said a witness in a German Criminal Court case of hes holding the indictment in his hands the until are usually in. But that wasnt the end of it during questioning the witness revealed that the other ministries also had access to the confidential files. But where they came from that bit he could remember is that the law he actually stated in court we call the ministry for the economy we have a special interest in ensuring that these manufacturers can survive economically thats from the man responsible for regulating odins exports. For decades heckler and koch has been a key supplier to the German Armed Forces and the police its considered to have systemic relevance. So does the Economics Ministry get special treatment to a company like that. We decided to ask a former economics minister is it my goblet. And also going to be because eventually began his statement by saying we are the ministry for the economy was the so the Ministry Wants this key manufacturer to survive. Yeah thats true but the export guidelines state that when it comes to arms and sponsor economic considerations are jobs are not to play a role as a kind of whats the legal position and i hope the court is familiar with the export of high clients. Back to the courtroom under further questioning by the presiding judge the official from the economics minister stated from the witness stand that human rights remora work of endeavor in dusty mencius of the people charged with safeguarding our highest value namely human rights in all constitutions in our constitution and they see it merely as a work of endeavor so if it happens to suit then well include that in it but otherwise were not interested includes the absence of the. Human rights as a work of endeavor. Thats not with the approval guidelines set up by the government state. Run fluted with descendants but this question the human rights situation in the recipient country plays a prominent role of the villein also coming from a legal background its clear that its an absolute test criterion and a deal breaking criteria. And indeed the official from the Economics Ministry admitted himself while testifying to the Customs Investigation Bureau that he realized the firearms had only been excluded from parts of mexico on paper. But the Economics Ministry denies any wrongdoing. The ministrys main contact at heckling cost was paid for by a lawyer he was in the docket stood guard but he was acquitted. Well day 2 of the trial peter biola stated that these endue certificates are and i quote the wrong instruments ineffective. This supposedly wrong instrument has for decades been the basis for all of germanys arms exports. Peeta by other had been the head judge of the District Court before moving to heckler and koch initially he was the companys Liaison Officer for the authorities and then later c. E. O. Throughout he was responsible for export applications and end use agreements. The export control Office Buffet also understands that the end user agreement is a binding document the fights not well done wait for shooting to our understanding of the law and use it difficult is it an integrity part of the licensing. Yet veteran legal expert peter by enough argued in court that and you certificates are not decisive for arms exports and he claimed to know nothing of the real work certificate from mexico but his correspondence with the chummy official at the Economics Ministry tells a different story. As i was aware of this email before its completely clear here the Economics Ministry is telling heckler and koch you cant export to these mexican states but these other ones are ok and yet in the trial all those involved maintained repeatedly that there had never been a list of positive and negative states its absurd that this is only turned up now. But thats not all. When the approval of arms exports to mexico did not appear forthcoming by a lot email colleagues suggesting they pursued what he called the political route. The company made donations to the constituency offices of influential politicians. We tried to speak to peter byelaw to as he emerged from the court one day. His lawyer d. T. H. Creedon fed blocked our cameramen pulling out the sound cable. Peter biola began brandishing his briefcase and his lawyer continued to attempt to obstruct us. Mr buyer what do you know about the Party Donations about heckler and koch. They were clearly not willing to talk about donations to politicians. In mexico meanwhile the families of the 43 missing students are still searching for the bodies of their loved ones. More than 60000 people are classified as missing in mexico presumed dead. And the appearance of the stones help us to locate graves. You can see these stones were previously underground so we know the ground has been dug over here you see the difference in the color of the stone was on the surface the other one was buried deep or.
