If we strike out in emotional response we will miss the boat. Some things in society rely on the individual to accept the responsibility to act civilly. In all walks of life there are those anomalies where the individual(s) cannot act within the law or other social more's The doctor, the lawyer, the judge, the nurse, the politician and even the plummer and house painter and military suffer from whacked out idiot sadists.
Sadly we just cannot operate on prior restraints as the sick mind cannot conform. So as much as it is hateful, we must deal with each circumstance as it comes up. Maybe stiffer penalties, but that would not restrain the sick minds.
We all must take a look at the larger puzzle. The percentages of mentally screwed up priests and cops and school teachers are a very very small sub 1.%, maybe like -- 0001 percent. You simply cannot legislate mental health.
So if we are looking at local police misconduct, which we are, it must be handled at the local level with clear civilian oversight and if need be civil disobedience. Vigilance by those most effected by the abhorrent behavior and local civil servants and activists are required.
So yes the local folks are liable for wrongful acts that cause injury. Juries of peers decide these things - even the risk of that going badly should force the LEA's to accept responsibility via cash. Although we all dang well know that cash cannot cure or replace the loss or injury to a loved one.
Yes, cash liabilities should force LEA's to act responsibly. Lawsuits and lawyers are not the problem. In most cases they are a better solution than riots which we all know are basically ruined by maniacs fanning the flames and committing violence.
Our system actually does quite well if you look at the ratios of a million cops against bad cops.
Don't let the media convince you that this is an epidemic. After all what you hear are the bad cops getting busted.
