The US media no longer make any pretence about their overt racism. Not one media member called the Dallas shooter a lone wolf, even though he was a lone wolf. He acted alone, unaffiliated with the Black Lives Matter movement, but good luck getting any racists in the media to admit that fact, to label a black shooter the same way as a white shooter committing the same crime.
And good luck getting anyone to admit the shooting in Dallas is the fault of US cops, courts and so-called "legal system". The murderers in Minnesota and Louisiana who murdered two black men bear more responsibility for the five dead cops in Dallas than the shooter. Minnesota governor Mark Dayton deserves credit for calling the crime a murder, yet for doing so the rightwing media and corrupt police establishment have sought to vilify him - the same police establishment that publicly celebrated when one of the six murderers in Baltimore was "acquitted" by a corrupt legal system.
