No one here is saying that, infact they're doing their best to keep from saying that. ATF, FBI, HLS, BPD, State Police, as well as local police from other towns are all there.
I was watching a live feed of one of the local news stations and they were throwing out the possibility. Also, there's a guy who posts on another forum who's listening to police scanner right now. He says there's been talk about it. Not saying one way or the other. Just that it's been said.
Here's the live news feed. The suspects have used explosives, in addition to guns, and right now they're bringing in the bomb robot.
