take some questions. just a second. i want to re-emphasize what the chief said yesterday. this case will be tried inside a court, so i have to be very careful with my responses. i do not want to jeopardize a future prosecution. >> you said that the items inside were explosives and excelerants. can you tell us what they are? >> so, again, i'm not going to elaborate on this. we are sending that evidence back for further exploitation to the fbi's lab at quantico and they will make the definitive conclusion as to what the substances are. >> can you talk about your personal experience with that. >> what would have happened if a neighbor opened that door instead of you guys? >> that's a very good question. it was an extremely dangerous environment. if a neighbor or an unassuming pedestrian walked in that door or god forbid a first responder,
