"Interesting. Hopefully you can understand why I came to the conclusion that raising police pay improves the quality of the police force."
If there's one thing Americans should have learned over the last 50-60 years, it's that throwing money at a problem never fixes anything. All it does is turn a problem into an *expensive* problem.
"Tell me, in your opinion, what is the best way to improve the quality of law enforcement?"
I don't know that there's a silver bullet, but a few things that I think would help substantially would be:
1) Make police officers personally (or at least communally) liable for legal settlements & judgments for misconduct, instead of leaving taxpayers with the bill
2) Make extending "professional courtesy" (the practice of looking the other way at police officers who commit vehicular and other minor crimes committed by police officers) a crime.
3) Require a civilian authority like a grand jury to investigate all allegations of serious misconduct (as they used to do), instead of having the police investigate themselves
4) Strip the police of many of the special legal rights & privileges they have acquired (in California, for instance, a "Peace Officers' Bill of Rights" contains all manner of extraordinary legal protections for police officers - among others, admissions to criminal conduct are inadmissible as evidence in court).
5) End drug prohibition
6) Prohibit police officers from publicly supporting political candidates
Mostly, though, I think the main problem is cultural. Police officers in America are still idolized by a substantial portion of the population, who will never cease to excuse even the most egregious criminal misconduct. These people always get on juries, and hence, it is nearly impossible to get convictions for police misconduct. This is changing, though - polls have shown that popularity of and trust in police officers is clearly declining. The problem is that I think we're past the point where the police would idly sit back and allow themselves to be stripped of any of their powers and privileges in any meaningful way - as the pendulum swings far enough that the public will demand changes and real accountability, I fear serious violence would be inevitable, and all sorts of unpredictable things happen when swords (or rifles) start being drawn.
