A friend of mine rode with a cop friend of his back and forth between Huntsville and Birmingham, AL on I-65 a year or two ago and he said they hit 110 mph on occasion.
I also read a headline recently about a bunch of cops getting tickets from speeding cameras and they were complaining that they shouldn't have to pay them as they have "diplomatic immunity". Whatever. This "do as I say and not as I do" crap sucks.
