Revenue generators

My pick of the year for the community's top revenue generators are police officers and the 'justice' system. I recently was awarded a ticket for which I had to go to court, and while I was there I kept track of how much revenue was generated over a 3 hour period. Lo and behold, it was over $15,000. I then extrapolated that amount to estimate an average of $150,000 per week and a monthly amount of $600,000. What that means is that over a one-year period the small court I attended raised over $7 million. Even if my estimates are off by 50% the city still profited by $3.5 million. What I would like to know is where, and on what does all that money gets spent? I know that my city brags about how safe it is, but I would wager that most of the local police officers spend their time on traffic duty, which (I believe) is a complete waste of time. Instead of being revenue generators perhaps the police and courts should concentrate on real crime. If their reply to this is that there really is not that much crime, then perhaps a layoff of police officers might make more sense than sitting them on the side of the road just waiting for someone to go 5 mph over the speed limit.
