They probably are shooting. Just not being reported. During the Los Angeles riots I was informed from a fireman later that most of the reported deaths were actually due to cops performing riot control. Think about the situation. Police don't even need to fill out forms or attend hearings for people they shoot, whose bodies will probably never be identifiable. The problem is the shear numbers of armed citizens and looters right now.
Just trying to distinguish between stealing bread and a cadillac.
