Cool being a Vietnam veteran, I have to ask, did you enjoy being spit on while returning to a country that felt you betrayed it?  Cool with being called baby killers and war criminals.  Take aside the police deaths that are skyrocketing.    Like it or not, the police sacrifice on a daily basis, they cope with injuries both mental and physical that you don't read about on a daily basis.  Ever seen a 2 year old crushed by his mothers car, a senior citizen abused by their children to the point they no longer thrive to live?    Ever tell a mother their kid is dead from gang gunfire?  These players don't take into account what goes into being an officer and dir, neither do you, you take it for granted.   Take a knee to support social injustice and discount the fact that the 2 year old that was killed by stray gunfire was exactly that, social injustice.  We ask for our police to put and end to it and then call foul when it doesn't look pretty.  Disgraceful.
