And??
Nothing you said contradicts what I said. There are factors why it is the way it is, but it is what it is. They do commit a higher amount of crime relative to their population of society. Thus they are going to have a higher level of interactions with law enforcement and thus they would have a higher level of situations resulting in deadly force than simply their representation in the population. Especially if disputes are solve "violently" as you say. It isn't due to racist cops.
Its one reason I support free birth control and more access to abortion. Having kids as a teenager with a nonexistent father (a common seen in the inner city) is a huge burden to overcome. Family planning would do a lot to improve people's situation. I'm 37 and it is not uncommon for me to dealing with grandmothers who are close to my age.
