Have heard the same from nephew, NJ State Police detective.
Heard the same from multiple sources too. The ISIS and Muslims around the world are creating a shoot Muslims first, ask questions later atmosphere. I have no doubt they would instruct several Muslim families to wear full regalia with hijabs and all to large events to attract attention and draw gunfire and sacrifice them for public sympathy. I say better to shoot one Muslim if there is any doubt than to have thousands of Americans killed from one bomb blast. If they are going to play that way we might as well make it worth the lawsuit and our lost time.
