I 2nd this. If you stop me or my wife the first thing I need to see if a badge, id, and warrant. Not one or the other. 2out of three at least.
This is exactly where the 2nd amendment and the Blue Lives Matter movements collide. If both civilians and police have the legal right to arm and defend themselves with lethal force, and neither has a responsibility to show restraint or demonstrate cause, then you have created a situation where an innocent civilian and a good cop could kill each other in self defense and neither would have done anything wrong.
