List the rational arguments in favor of the so-called "right-leaning" point of view (OP's term, not mine) with respect to the Pretti killing. Spoiler: there are no such arguments, effective or otherwise. To apologists it looks like a Rorschach test; to normal people it looks like a snuff film, brought to us by the same studio that is now distributing child pornography.
Meanwhile, it's possible to favor free enterprise, (genuinely) smaller government, low taxes, free trade, and other so-called "right-leaning" perspectives without joining a slack-jawed personality cult that demands that you deny the evidence of your own eyes.
In my country, lifting a finger against an officer on duty will land you in big trouble. If you got a gun on you and you resist arrest, like happened in this case, you are absolutely getting shot. I can’t really understand you Americans. What do you think an armed person reacting to arrest is going to do with that gun given the chance? If you were a cop would you take chances?? If you did you wouldn’t be here complaining about anything as you would be dead.
