why does nobody ever use the term 'male lives matter' with policing and prisons?

it is evident that there is unjustified discrimination against african americans relative to whites&asians when it comes to police shooting and prison sentences. however it is just as evident that men get longer prison sentences for the same crime and are less likely to get aquitted for the same crime. also violent male criminals are 2.5x as likely to get shot by a cop as violent female criminals. 96% of police shootings are commited on men while 89% of violent crimes are committted by men. and some reply saying oh, its jusfied since men are more likely, however if that were justied, then you are saying racial profiling is justified because african americans are more likely to commit violent crimes than whites&asians. so why are people focused on one group and not the other???? when they are both equally unjustified actions by our brutal law enforcement.
