Dude! What's with all these brushes with the law.
Seriously though, I had a buddy many years ago (20+) who right out of college joined the sheriff's dept and told me that routinely on patrol they would go into "intercept mode" whereby they would cruise at 20-25 mph over the speed limit in the hopes of catching up to someone up to no good (speeding, reckless driving etc). And it was all perfectly legal. This is what he told me.
