Today president obama put limits on the heavy weaponry that the federal government has been making available to local Police Departments. We have more on this now from our chief White House CorrespondentMajor Garrett. Reporter these scenes of police dressed for battle in ferguson, missouri last summer provoked a National Debit on the militarization of local police. This was president obama in august. There is a big difference between our military and our local Law Enforcement, and we dont want those lines blurred. Reporter today in camden, new jersey, the president took steps to clarify those lines issuing an executive order banning the pentagon and other federal agencies from sending Police Departments surplus military hardware, like tanktreaded personnel carriers,a grenade launchers and even bayonets. The pentagon shipped more than 6,500 bayonets to civilian Law Enforcement agencies over the last two years, and the Defense Department says since 1991, Police Departments nationwide have received 175 grenade launchers and 101 personnel carriers with tanklike treads instead of wheels. Weve seen how militarized gear can sometimes give people the feeling like theres an Occupying Force as opposed to a force thats part of the community thats protecting them and serving them. Reporter but most military surplus items will continue flowing, like these mineresistant personnel carriers used by police in the recent unrest in baltimore. Police can still receive riot shields, longrange firearms or night vision goggles. There are new rules. Law enforcement agencies requesting surplus gear will now have to announce their request publicly, explain how it will train its officers to use the militarystyle equip and comply with measures to track it. In addition to these transparency moves 21 cities have pledged to do more. Publicizing for the first time precise numbers on officer involved shootings and traffic stops. Scott, the president said this information will increase Public Awareness of Police Tactics and their consequences. Pelley Major Garrett tonight, major, thank you. There is an investigation this eve intoong what brought down a u. S. Marine aircraft in hawaii. The osprey crashed and caught fire yesterday during training exercises. One marine was killed. Four others are in the hospital. The osprey is a tiltrotor aircraft. It takes off and lands like a helicopter but flies like a plane. It has been used extensively in iraq and afghanistan. Iraqs u. S. Trained military suffered a serious defeat yesterday. It was chased out of the city of ramadi by the Islamic Militant group known as isis. The u. N. Says 25,000 civilians are fleeing the city now. Ramadi is a city of 500,000 70 miles west of baghdad. It is the capital of a province that was once secured at the cost of 1300 american lives. Clarissa ward is following this. Reporter it is the biggest military victory for isis since last summer when the militant group left iraqs second largest city of mosul. After four days of intense fighting, iraqi authorities said that 500 people were left dead, thousands of civilians fled as the black flag of isis was raised over ramadi. The fall of ramadi came in spite of intensified u. S. Efforts to push back Islamic State fighters with at least 180 air strikes on the city in the last month. As isis militants flooded in, Iraqi Security forces appeared to flee. Policemen abandoned their stations leaving behind their americansupplied weapons and equipment. Ramadi is the largest city in the mainly sunni province of an anbar, which stretches from the western edge of baghdad to syria and jordan. Anbar was the heart of the insurgency against u. S. Forces during the iraq war. Nearly 1,300 u. S. Marines and soldiers were killed there. Last month iraqs Prime Minister promised a sweeping new military offensive in anbar to rout out isis militants but with the retreat of the iraqi army, there are few appealing options. Now the Iraqi Government has mobilized its shiite militias, some supported by iran to try and reverse its losses. It is a controversial move. Many fear the presence of shia Paramilitary Forces will reignite a religious war with sunni and tribes in anbar. Pelley and clarissa is joining us now. Quick question the u. S. Government has said in the past that it will not provide air support if these shia militias controlled by iran are in the fight. So where does this leave the u. S. Now . Reporter well, scott the u. S. Is in an awkward position here, as you pointed out during the battle for tikrit, the u. S. Military initially sat out saying it wouldnt participate while those militias were operating on the ground, but today they appear to be walking back from that position saying the shiite militias do have a role to play as long as they are operating under the control of the Iraqi Government. Pelley thats an indication of how difficult things have become. Clarissa ward reporting for us in beirut. Clarissa, thank you. There is a humanitarian crisis off the coast of malaysia this evening. Thousands of migrants are stranded at sea. Many are muslims who fled religious persecution in burma.

The train slowed noticeably as we went around the curve where the derailment happened. Passenger Bryan Cummings was on that Early Morning train bound for new york city without any hesitation. One of the safest ways to travel and, you know, this is the way i want to go. Reporter fall regulators required amtrak to activate Safety Technology at the scene of the derailment that would stop a speeding train before it got to that curve and amtrak is also adding speed limit signs as well as reviewing the posted speed limit for curves throughout their system.

Its enormously frustrating for up to the 40 million americans that have it because up until now there has been no test. So patients often go from khurana to doctor to rule out other conditions. When everything comes back negative, they say well, it must be ibs. Now theres a new blood test that can help make the diagnosis. Pelley how does the new test work . Its based on research after many years by dr. Mark pimen tell and his colleagues at cedarssinai in l. A. Says it may develop after a bacterial toxin found in foods poisoning. It resembles a Vital Protein found in the gut. The immune system may confuse the two and antibodies continue to attack the intestinal track wrong after the toxin is gone. The test shows whether that is occurring. The test for these two antibodies. Whats so important is that not only for all the millions of americans with ibs they can say its not in my boars head, its showing something in the blood, but it suggests a possible peck anymore. Now that we have a blue, maybe we can come up with better treatments. 40 million americans. John, thank you very much.
