And my problem was that he was saying that the officers were not accountable, which is not true. They are being held to account. Every time. He may not like the outcome after the accounting. If he does not, he should address that particular case, not make the broad and false statement that officers are not held to account for shootings. They are.
P.S. I have often said that cops are citizens too. In most matters, they should be held to the same standard as all other citizens. I see two exceptions: They are (at least supposedly) highly-trained professionals. As such they should be held to a higher standard when it comes to those actions for which they have been trained, just like any other well-trained person would be. The second exception is that they have been given very specific authorities that they may exercise in very specific circumstances, authorities that other citizens don't have. The problem arises when an officer thinks he has an authority that he does not or when exercises an authority in a situation where he does not have it.
