From a recent Harvard Study, and it refutes your "systematically murdered" claim.
Fryer concluded that the racial bias narrative is demonstrably false when it comes to police-involved shootings.
Police are not more likely to fire on blacks than whites. In fact, blacks are 20% less likely to be fired on.
Blacks and whites involved in police shootings were equally likely to be carrying a weapon.
Blacks are more likely to be treated worse by officers when it comes to physical contact.
The notion that police officers’ accounts are biased and unreliable is largely a myth.
In 2015, for example, 50% of the victims of police shootings were white, while 26% were black. Some have tried to argue that this is evidence of racial bias against blacks because they represent only 15% of the population; however, as Heather Mac Donald points out, blacks account for a disproportionate percentage of major crimes, including 62% of robberies, 57% of murders and 45% of assaults. Another example of de-contextualized data is that showing a higher percent of unarmed blacks who are shot than unarmed whites, but as both Mac Donald and Fryer found, when the details of the cases are included, such statistics turn out to be misleading.
