I spoke with a leo from a large CT city that just finished doing long shifts in Newtown. During our discussion he flat out told me that he and many fellow officers WILL NOT go into a building to disarm a criminal. They will not risk their life for a Bushmaster.
none of that conversation makes any sense. First how would they even know the make of the weapon? second, cops go in after armed criminal, active shooter or not on a regular basis. THIRD, cops are not rained to "disarm" active shooters to begin with.
