You are right on that, Bill, it is a big business in my area........especially with illegals.
90% of the arrests in our local paper everyday are illegals that were caught DUI, suspended license or no license, no tag, and no insurance. If that were me, they would throw me under the jail. But the immigrants get a heavy fine (which they eagerly pay) and then get turned loose to change their name and do it again next week. The system isn't worried about sending them away because they make the county/city a surplus of money.
I went to municipal/traffic court once just to watch the dog and pony show. I watched as the 'judge' fined one guy $5000 for a third offense DUI/License/Insurance offense.....and the guy pulled it out of his pocket and paid the clerk. The judge then suspended the jail sentence, since the guy paid the fine.....I left, shaking my head.
