They do. But they are very very very rare. And that is the point of the article.
Yep, that's what the LEO propaganda tells us. Reality is way different.

Law enforcement in the U.S. are killing citizens at more than 90 times the rate UK law enforcement does. By no reasonable standards can that be called "rare". In that egregiously high number of killed citizens, Blacks are still over-represented, despite Black parents having "The Talk" with their kids as they enter the most rigorously profiled age group, so as to prepare them for encounters with the cops, reducing the likelihood to have their kids killed. White parents do not, need not, do that.
Of course, no LEO propaganda can do without pointing to black-on-black crime, as the retarded notion has it, excusing away murderous cops. The conclusion should be that cops do not consistently serve and protect black communities and neighborhoods, neither from the systemic racism with their own ranks, nor from the rampant criminality in those neighborhoods.
