Shoppers at a Walmart outside Rochester, New York were greeted with an usual offer on July 16, 2016: the invitation to hug a cop.
"We just want to better the relationship between the community and the police."
"I just saw the kids, they needed some help, I helped the kids."
Recent events in Baltimore, Ferguson, New York or wherever an unarmed black man has died in police custody remind me of something I learned long ago when I was on the police beat: There is nobody better than a good cop. There is nobody worse than a bad cop.
