I really do not see how that could reasonably be assumed to be possible. These are people who make near minimum wage and face death every day, but when they screw up on the job, like everyone does, they should face jail time? Everyone makes huge colossal, bone headed mistakes in their careers. It is impossible to avoid all accidents, particularly in such tense scenarios. If the media can only point to 1-5 obvious mistakes a year, that is 1-5 out of millions and millions of incidents and altercations with criminals and other citizens. At the end of the day, as a police officer, you have far far far more danger of murder hanging over your head every day than the danger that Black men have of being killed by police (research seems to show a ration of significantly over 10:1).
