Oh so keeping the roads safe is a problem now? Did you know that traffic violations are just about the ONLY crime you can catch people while they are actually violating the law? Patrolling neighborhoods does nothing to stop crime, because the chances of catching someone burglarizing, raping, robbing etc. are slim to none. Actually, you pull somebody over for a "technicality" like a broken tail light, and you find out they've got warrants out for other violations. In essence, random patrolling will catch more hard criminals than randomly expecting to drive by a crime happening.
