The issue is really one of balance among the various parts of the criminal law enforcement system. At the front end, there are cops. The more cops there are, the more criminal charges there will be. Thus, the number of judges, court staff, prosecutors and defence lawyers needs to be in proportion to the number of cops; any time the number of cops is increased, the number of judges, etc. needs to increase accordingly. The more judges there are, the more sentences will be pronounced. Thus, the more judges there are, the more prisons, prison guards, probation officers, parole officers, etc. there need to be.

One of the big problems is that governments react to perceived crime problems by increasing the number of cops without allowing for a corresponding increase "downstream". This is what is clogging the criminal courts.
