Then you lack attention skills.
When cops kill UNARMED men and women, the right is every bit as outraged as anyone else. Yet, you fail to detail the circumstances of those killings. Cops have a right and a duty to ensure that they don't end up killing themselves, which means when a citizen interacts with a cop, they have a duty and obligation to not act in a manner that is threatening to the cop.
We all have social skills that we must abide by.
SOME cops have a superiority complex, but the OVERWHELMING majority of them are just trying to give back to their community and make it home alive, every single day.
So, until such time as you put on a badge and deal with the dregs of society on a daily basis, perhaps you should endeavor to learn the truth.
Those cops in Texas, who were cowards are NOT the norm in Law Enforcement.
