According to CNN, Harris County Sheriff Ron Hickman has stated that the murder of Deputy Darren H. Goforth is because... wait for it... #blacklivesmatter
Authorities cited anti-police tensions that have spread nationwide over the deaths of unarmed African-American men at the hands of white officers. Hickman said this has led to a "dangerous national rhetoric."
"When the rhetoric ramps up to the point where calculated, cold-blooded assassination of police officers happen, this rhetoric has gotten out of control," the sheriff said.
Here's summary of my thoughts on this: Being a police officer is dangerous. This is as it should be. The fact that it's dangerous implies the very real need we have for police officers. It also implies the measure to which we should be grateful to the courageous people who willingly take up such a dangerous profession.
Willingly. Please remember that no police officer is in that job because of an accident of birth from which they cannot escape. On the other hand, an African-American man in the US is in 373% more mortal danger from violence of any sort than a white man. And in 2,100% more mortal danger from a police officer.
