This was handled incorrectly. Shoplifting. Really? From a dollar store at that. Someone could've lost their life over a dollar? There were 2 small children that the police ignored in the threat to their parents. Couldn't this have been handled in a better way? Sensitivity training needed? It's an example of what the world is like when police are afraid.
"Unacceptable"? = understatement; euphemism.
Some acts are unacceptable; others (like this one) are despicable.
