different hospitals. >> how have, we were discussing this a little bit earlier in the show. how have procedures changed post columbine? >> after columbine and after 9/11, we really changed the way we look at response and preparation to disasters going from a response to a preparation mode. so our hospital like our partners across the front range, regularly practice for multicasualty events, so it becomes much more a question of preparation than of reaction. >> tell me what source of injuries you saw. i was speaking with another hospital today and they were saying many of the victims had three to five gun shots. they were treated for chemical burns as well. what were you seeing? >> we were seeing gun shot wound victims. some with more than one.
