Sigh... Okay, here we go again.
Props to Law Enforcement, in that they execute 10 million arrests and 40 million traffic stops a year and there are only 1000 or so times it escalates to a fatal incident. So the cops really do get it right 99.998% of the time.
Of the 1000 times, they do use lethal force. Usually, the other guy has a gun or a knife.
But the times that are unacceptable—Sonia Massey, George Floyd, Laquan McDonald, Tamir Rice—usually involve someone who had absolutely no business having a badge or a gun.
Now, one more point. A reason our cops are sometimes a little too trigger-happy is because we have an armed populace to start with. US cops shoot 1000 suspects a year. British cops are usually in single digits any given year. Most other industrialized nations are in low double digits.
