The police deaths have everything to do with BLM and their hateful propaganda.    No matter what is really happening they are brainwashing most black people into thinking that they are the only ones that are ever detained by police, arrested by police,  stopped for a broken tail lightor expired tags  by police, stopped for fitting the description of a perp by police,  or shot and killed by police.    They refuse to admit that happens   to people  of any other color and that it happens just as regularly to white people as it does blacks because they brainwash other blacks to fear for their lives with their rhetoric........and  it doesn't fit their "revolutionary" agenda if they were to admit it.  
Screw BLM.   They are nothing but terrorists themselves.
