Any statistic is true of a small subset of the population. To use your example of black people: Killed in 2018: Black or African American 2,925 Police killed 1,098 people in 2019. (I can't find exact numbers by race) Again, I'm not arguing that there isn't police bias against minorities, that they aren't disportionally affected, or anything like this. But the facts simply show that the police kill less people than other people do, so it seems like a stretch to say they're more of a threat. In regards to the other point: that may be the case, but that isn't what "abolish" and "dismantle" mean. I still don't see how you avoid some amount of armed protective personnel (to deal with shootings or robberies) which are basically police.
