Obviously, I used emotional hyperbolic language and I admit it. There's no way I (or any observer after the fact) can definitively tell if any one person is guilty or not, let alone make a factual statement about many people.
HOWEVER, having lived in cities and neighborhoods with crime problems (eg Baltimore,Philly), I am aghast at how dysfunctional the criminal justice system is. If you look at public court case records of offenders, you'll see a peculiar pattern. Robbery, Burglary and violent crime offenders are RARELY limited to ONE case. Usually, there are several or even more offenses. The outcome of these cases is almost never a clear-cut "guilty" followed by prison time. Instead they're a convoluted series of pleas, followed by a drastically reduced sentence or PBJ (probation before judgement). A PBJ is effectively nothing to a repeat offender, because many continue to be charged with crimes WHILE ON PROBATION, and there are virtually NO additional consequences for those violations of probation.
The kinds of problems I am talking about are described in detail by Paige Croyder (http://pagecroyder.blogspot.com/). If you're interested how criminal justice "works" in Baltimore, she's the best resource.
The angst felt by the laywer who quit to become a clown, is not a surprise. Anyone who has a conscious will have a difficult time with being a lawyer in a criminal case (this goes for both sides).
