If Whites aren't protesting for them, why would Blacks? ;)

Nice try in your attempt to question if they are just ra___!  

Such as:

Victims killed during the commission.
Perpetrators killing during the commission of a robbery or other crime (besides the murder itself).
The political leanings or Party affiliation of the killer.
The political leanings of Party affiliation of the victim.
The religion of either the victim or killer (Presumed or actual)..
The economic status of either the victim or the killer.
The sexual orientation of either the victim or the killer.
The victim-killer relationship (domestic violence? Arbitrary killing? Business disagreement?).

So this is sparked by the Black Lives Matter movement, which includes by definition a great number of economically disadvantaged communities. The BLM movement has no stated political agenda except to make people aware of the problem facing their communities. Police often feel the brunt of their criticism.

Police are at a real disadvantage in the rectification of crime in African-American communities or any high-crime community.

Police generally become involved after a crime has been committed or when there is suspicion that a crime is going to be committed. After a crime, the focus can easily fall on the police and on the prior relationship the perpetrator had with police. The community efforts to reduce crime (along with state and municipal efforts) may or may not include the participation of the police. But economic factors and education are major elements where, however good their intentions, the police are limited as to what role they can play in improving that.

If the victim's history, or the criminal or suspect's history shows prior police involvement, the police can be critiqued for how they might have prevented the crime as well as any incidents that might have provoked the suspect. The talks police officers have with potential troublemakers, especially youth, that prevent individuals from embarking on a "life of crime" cannot be quantified, measured, or brought to public awareness. So the good that policing a community does remains unknown while any mishap receives immediate publics attention with sufficient data to be investigated and judged.

So in terms of gaining an understanding from the statistics that are useable in the reduction of crime, simply knowing the race, sex, (age, which isn't included in the referenced chart, but known and documented somewhere), and ethnicity seems insufficient.

Ice cream sales and deaths by drowning are two statistical charts that rise and fall almost in unison. You could place a transparency of one over the other and find very little variation. Does that mean that selling ice cream leads to people drowning? No, what it shoes is that people go swimming mostly in the warm summer months when ice cream sales are at their peak, and that people eat less ice cream during the winter, the same months when it is too cold for most people to go swimming.
