If black criminals regularly complied with arrest, they'd be alive. Since blacks murder each other 7 times per day, everyday, you'd think that would be more important than black criminals that die less than 10% of the time. I'd say an average of 50 murders per week, week after week, means many aren't being solved. Is that what you mean by "working properly"? I'd say a 20% success rate is more of a dismal failure, pal.
City data over 19 months show police solved 47% of murders with white victims and 22% with black victims.
