I used to be an explorer (community service policy program) and I destanctively remember being taught that when you encounter a potentially dangerous situation there's different levels of approach. For example first you use mace/night stick/tazer then as a last resort your firearm. I got pulled over recently for speeding and the officer walked up to me with his hand on his gun. (I'm white and was pulled over in a 98% white low crime subarb). It seems like there has been some sort of shift to police immediately justifying have thier guns ready and willing to kill. Has there been an actual shift in training procedure or do we just see this because of what is reported through media?
