This crap always happens when and where no one is able to shoot back.
I learned something way back, early on in the development of my awareness. I'll share it here: "When guns are outlawed, only outlaws will have guns." Those who abide the law are then set up to be victims - not only by the unlawful, but by the law and those who create the law.
One must look beyond the law enforcers to those who create the law. It all starts with the law.
