The president is silent. Violent crime is down dramatically the last two decades and mostly in black neighborhoods through better policing and tougher sentences pushed by the Clinton administration. This is a George Soros funded organization; the man is up to no good and promotes socialism, although he himself is mega-rich.
When Sarah Palin used the word "target" in her political ads, the Democrats yelled she was to blame for the Gabby Gifford event shootings. But it's crickets from liberals about "black lives matter" and "hands up don't shoot" hate lies and their connection to the deaths of three policemen in one week.
President Obama’s attacks on police began the first month of his presidency when he blamed the Boston police for responding to the call of a break-in at Louis Gate’s home. He said they acted stupidly because they questioned Professor Gates and didn’t know it was his home. Eric Holder continued the drum beat and they both have sent administration representatives to funerals without considering whites, Hispanics or blacks killed by blacks.
The crime rate for blacks is 8x that of whites, which means black families are the victims and suffering. Even so, crime has dropped drastically in the last two decades after the Clinton administration released money for more police. Now the Obama administration (along with Baltimore and New York mayors) wants to reverse that amazing life saving trend.
According to the US Department of Justice, blacks accounted for 52.5% of homicide offenders from 1980 to 2008, with whites 45.3% and "Other" 2.2%. The offending rate for blacks was almost 8 times higher than whites, and the victim rate 6 times higher. Most homicides were intraracial, with 84% of white victims killed by whites, and 93% of black victims killed by blacks. (which means far more whites are victims of black offenders than the other way around)
