He witnessed the attack and he was shocked and also the response or lack of response by barge employees. And when they spoke with the mayor and he has Harsh Criticism for bart. Reporter the mayor doesnt believe the station is adequately staffed and employees that were there did nothing to help. Reporter it happen on the south side of the Richmond Park station. A group of teens surrounded a man and punched and kicked him while some took video. They were all running back and forth and they all have their cell phones out. Reporter the richmond mayor was about to take a bart train and he saw the attack answer called 911. White police responded, but the time they arrived the teens were gone. The victim was taken to a hospital. The mayor told me he is not was happy with the response to the assault. Richmond connected him with bart police even though its in the citys jurisdiction. It was pretty frustrating. I think it exposed a lot of flaws in emergency response. Reporter that is not all. The mayor took this photo of workers in a nearby truck who didnt seem to take action. They were watching or asleep, i dont know. Reporter he didnt see the station agent at the booth. He says that bars needs to bart needs to step up patrol. I wouldnt want to be in a security situation in that station because theres nobody there and nobodys going to help you. Generally speaking, bart is safe. Reporter the police chief says the agent was on duty somewhere in the station. He says that transit officers are responsible for two to three stations. There is a we way we can guarantee a Police Officer. As for the bart workers sitting in the truck, they were maintenance workers. They have no Law Enforcement training. We would ask them to be a good witness. Reporter many say the bart needs to be more proactive. Police need to be in the station for the issues. They need to be trained. Like i said before, this is where im front. At the same time, if there were employs around close by. Reporter the mayor wants to have a chat with bart police to iron out air it any jurisdictional issues in and around the station. This incident comes as part season uptick in crime something we been reporting on. They struggle with the shortage of officers. We have been looked in looking into the other stuff force. Reporter theres never a cop around when you need one. The reason why thats true but somewhat unfairly true about bart. Reporter when people complain they never see a bart Police Officer, deputy bart police chief offers is to riders. They may not see an officer every day, we are out there and effectively patrolling the parking lots, stations and trains. Officers are responsible for two or three stations. For the number of cars and people that travel through a station, it is tough to be on the trains and the platforms and in the station and the parking lots. Reporter currently there are 185 sworn officers and they are trying to hire 40 more. Bart 47 stations are sprawled out over 112 miles of track. And currently has 669 cars to make up its trains. It has 50,000 spaces in its many parking lots. By definition, that means the bar Police Officer police force is spread thin covering multiple stations per shift whether or not the trains are operating. We are responsible 24 7 for the bart district. We have vehicles left overnight and we have people that come onto the property to commit crimes. Reporter coming up at 5 00, we will explore what experts say about the adequacy of bart pd and what would be needed to remedy it which is a whole lot of money. You talked off camera about people taking matters into their own hands like they do on planes. The Police Advise against that. On an airplane, these people have been prescreened. On a bart car or transit bus, you dont know what kind of person you would be facing. Be a good witness instead of a dead one. Its a bad idea to try and take matters into your own hands. The other problem for bart police, if there was an officer on a commute, he is jammed in their with everybody else in that car. If something goes wrong several cars back, how do you get there . It is a numbers game. Do the math. For cops for station. As this thing gets bigger and bigger, they will need more and more police. If we want to have a greater concentration of police, we will have to vote for it and pay for it. If you would like more information about bart and potential staffing issues, head over to ktvu.

That gun belong to an agent with the federal bureau of land management. Lopez sanchez attorneys say they want to call that agent once the trial starts it has all the physical traits of an accident.

He tweeted earlier today he had verbal government approval to build its final or highspeed transportation from new york to washington dc. He says that can break ground by the end of this year. For more on the future of the hyperloop, im joined by tim higgins. Okay. For of verbal government approval, what does that mean . Nothing is signed on the dotted line. Maybe he got a knob a nod of someone saying they like the idea. The white house told me they been having positive conversations with elon musk and some of his people regarding the hyperloop. That is where we are at. For folks at home that arent familiar, its a plan to whisk people from new york to washington and do so quickly like dirty minutes. Were talking about tubes that would be vacuum sealed and youre in a little pod and you can get there in 29 minutes. How realistic is this . This is technology that hasnt been proven on that grandscale. There have been startups to creating test versions of this and theyve run into delays. It is something elon musk has been talking about for years. This tweet though. He needs to do some clarifying. He originally set of gotten this verbal agreement, government agreement.

The Washington Post reports President Trump asked advisors about his powers the pardon eight family members and himself in connection with special counsel Robert Muellers investigation into russia. For more on that, im here with professor levine. What do you think . Lets do pardon oneonone. It is that it is in the constitution. An express power to the important limitation is only for federal crimes. And so if say youre talking about stay crimes, that is for governors and not for the president. And then, the power is really wideopen. There are no standards. President s have created procedures, usually is done through an office of Pardon Attorney Office in the Justice Department who carefully looked at these cases. The president can do whatever the president wants to do. You dont have to wait until somebodys been convicted of line. One of mr. Trump were to do this in the weeks to come . If he pardon his son, his sonin law, his associates. You would assume it will cause a huge uproar to do that. To interfere and to an Ongoing Investigation you would think that would cause a huge problem and might possibly lead to impeachment proceedings. There is a political price to be paid for using the pardon power. Sometimes has been very controversial. President ford, jimmy carter lost to jimmy carter because of that.
