directives, these orders if you will, coming out of raqqah, syria, from isis. >> bob, carrying out the directives, carrying out the orders of raqqah in syria, does that seem likely to you? does it even matter here whether it's inspired or directed by isis? what's the significance of the difference? >> well, i think the fact there was a uniformed officer attacked tells a big story. some people here are responding to the call from raqqah to attack people in uniform, whether it's military or the police. this is really has taken a turn for the worse that people are responding and apparently this man was a convert. and somebody very difficult to find out. i mean, to become a muslim, so become a convert to the islamic state, all you have to do is say the -- go get a stolen gun and you can carry out this war here. and the police should be concerned because i know they suspect there's a lot more of them out there ready to go after them. >> answering the call, tim.
