What you propose would be a gift, and at the expense of the victim no less.
The victim supposedly is trying to send a message,
Shouldn't that message be sent to the ones that actually make the policies
Perhaps we should "retrain" burglars to find a new profession, and chastise the city for making it illegal to take that which doesn't belong to you?
Ridiculous comparison
Burglars know that what they are doing is illegal and no laws have been passed by their employers to make them think otherwise
The city is certainly at fault for passing an illegal law, but the officers are just as much at fault for enforcing it. They would not enforce a law which said "all blacks out at night must be executed on sight", would they? If (God forbid) they DID, I'm sure everyone would be calling for their heads - literally.
Another bad comparison
It is universally known that laws aimed at oppressing blacks has been shown to be unconstitutional and no city would even attempt to pass one giving an officer the reasonable impression that it was a legitimate law
Charging the officers with whatever crimes they committed as well as holding them personally responsible in a civil suit is not crossing any line. It is the least these miscreants deserve. "Retraining" is a slap on the wrist and simply sends the message to government that it may do as it pleases as long as it re-writes the policy when someone raises a big enough stink.
Cruxifying the officer does send a message to all other officers, one that may have unintended consequences
Do we really want officers that are too meek to perform their legitimate duties as well as the ones that we find offensive
Retraining may just produce a more knowledgeable officer that will pass that knowledge on to others
Your way would force good officers to rethink their line of employment
No officer can possibly know all the laws.
We have confirmed die hard gun advocates here that don't even know the very basic laws of buying and owning a gun and that is basically the only laws they have to be concerned with here
The department and the city are to blame for the law and instructions to enforce that law, the officers are only guilty of trusting the superiors that they are supposed to trust for information and education
