Holmes apparently considered targeting an airport, but decided against it, not wanting his attack to be confused with terrorism. The message is, there is no message, holmes wrote according to files. He chose a theater, even though holmes put the chances of being captured at 99 . The bullet point says three options of attack. Reporter jurors who will decide on a plea of not guilty by reason of insanity followed along with their own copies as the notebook was read aloud.

Jericka duncan reports this is all meant to ease the tension between the black community and a police force that is two thirds white. Today, may 26, 2015, marks a new way of policing in the city of cleveland. Reporter in the settlement the city promised they will document every use of force down to pointing a gun at someone. Officers cant use chokeholds or force to stop someone from running away. Theyre not allowed to fire from or at moving vehicles unless use of lethal force is justified. The city will also create a Community Police commission and appoint a civilian the lead the internal affairs division. Cleveland mayor frank jackson. I think that we need substantive change and we need to get it done rapidly. Reporter other key changes include emphasizing deescalation and creating distance between the officer and potential threat.

Historic drought is no now in its fourth year today the metropolitan Water District voted to homeowners los angeles and other parts of Southern California another 350 million to replace grass with plants that use less water. The program had already run through its original budget. Today, iraq said that it will counter attack after a humiliating defeat for its army and for u. S. Policy. Last week, the Extremist Group isis chased iraqi troops out of ramadi, the capital of a major province. The american strategy relies on iraqi soldiers, but this weekend defense secretary Ashton Carter said the iraqis lack the will to fight. Also air strikes by the United States are hamstrung because no americans are on the ground spotting targets. David martin shows us why that matters. Reporter the f16s are cleared hot, meaning free to drop their weapons on the target. On the ground, friendly troops are in a firefight with the enemy. Two mark 82s. explosion reporter mark 82s are 500 pound bombs. This is an exercise in louisiana. But the bombs are real. Troops are u. S. Army. Have him come in parallel. Reporter but the man calling in the strikes is air force Sergeant Danny aboy. I am the Critical Link between troops on the ground and the air force. Reporter aboy is what the air force calls a joint terminal attack controller. You are approved to strike anything within 100 meters. Reporter the man who talks pilots like Lieutenant Colonel matt casey on to the target. Hes able to talk directly to the pilots so in the minimum amount of time we find what the army is asking us to look for. Reporter and hes your eyes on the ground. He definitely is our eyes on the ground. Reporter there are no Terminal Attack Controllers on the front lines with iraqi troops, so pilots flying strikes against isis have no eyes on the ground. Captain sean holche is an f16 pilot. What difference does it make to you whether or not you have an attack controller on the ground . Its important. It speeds up the process and it helps us to be more accurate with delivering those weapons. Reporter and nowhere are eyes on the ground more important than in urban combat like the battle for ramadi. In urban combat, everything is closer, like fire from rooftops. The closer it is, the more coordination it takes. Reporter the closer it is, the more you need an attack controller on the ground. Yes, absolutely. Reporter pentagon officials acknowledge strikes flown with controllers would be more efficient. But they are not willing to put americans on the front lines of a battle the iraqis have to win for themselves. Pelley and david is joining us now at the pentagon. David, it was a remarkable admission when secretary carter said this weekend that our iraqi allies lacked the will to fight. Why did he say that . Reporter scott, counting both police and soldiers, the pentagon estimates the iraqis had nearly 10,000 troops in ramadi, while isis had about 900. So the iraqis have had a 101 advantage, yet they retreated, leaving behind much of their u. S. Supplied equipment, including about a half dozen tanks. Pelley and u. S. Taxpayers, its been about 25 billion on the iraqi army. David, thank you very much. Today, iran put a Washington Post reporter on trial for allegedly spying for the u. S.
