I have no problem giving great deference to cops on the street, and the split-second survival decisions scofflaws and criminals often force them to make.
I have a great deal of respect for police as well. The vast majority of them do a very good job under very trying circumstances, a job I don't think I would be very good at. But their job also comes with a great deal of responsibility. The responsibility to abide by the law and not abuse their authority. The responsiblity to use deadly force only as a last resort. Tens of thousands of cops go out and do their job every day and stay within those guidelines. When they don't. When they abuse their authority, as I believe that cop in Texas did, or when they use deadly force as a first resort rather than last, as I believe this cop did, then I think they shouldn't be trusted with the authority the badge gives them. And when they cross the line and kill people without cause then I think the full weight of the justice system should land on them. Unfortunately the record of either of those occuring when they should is very spotty lately.
