they have access to c4, access to explosives. everybody knows that. so you weren t surprised by what we saw in paris? i was shocked by it, not surprised. i find that we all know, because we re following the threat streams, that any individual who wants to strap a suicide vest around them can walk into any public event in most places in the world and blow him or herself up and destroy people with them. so that s the nature of terror. that s why terrorists are called terrorists. they spread terror. reporter: we also discussed that latest threat from isis, the propaganda video that came out that threatened washington, d.c. as a target. the secretary said it s nothing new, we ve heard these sorts of things from isis before. we also talked about the growing number of governors who say they do not want to accept any syrian
facility from which you heard the one witness say earlier this is hell. as we reported earlier tonight, catherine harriage says it may take upwards of a dozen people to coordinate this attack at six separate sites. why officials are not preparing a statement, accomplices may still be on the loose. catherine, do we know now who is responsible for this? megyf, tonight, there are two separate threat streams. one involves credible isis accounts. these are accounts that are sell bratorial in their tone. they are not claiming responsibility for the attack itself. we saw a similar attack on the satirical magazine. the blame is ultimately fixed
