No one is rationalizing anything but you. So many innocent people killed by police every year, but the media never covers them, and instead picks the violent felons dying doing dumb shit like doing meth and fentanyl and resisting arrest to support because TV and Twatter said so. You are fucking brainless automatons. Furthermore black on black violence kills many multiple times more than police do, but lets all pretend that doesn't exist cause MUH RAYSHISM and BOOTLICKERZ!
The media covers a lot of police killings of innocent people -- it happens all the time: that's the problem.
Regardless of the situation, death by execution is not a fit punishment for doing meth and fentanyl. Nor is it for being a "violent felon."
Again, you said he resisted arrest. When? Nowhere in any of the video footage was he shown to be "resisting arrest."
Keeping sucking on those boots if that's what makes you feel less afraid of the world. It is big and scary out there, after all.
