There is a group of 2-5 motorcycle cops on the right hand side of S. Carrollton (northbound side of street) directly at the entrance to 1-10. It appears that they are checking for registration/inspection stickers, not speeders (I have not been stopped), as they seem to eyeball the drivers side of each car in a line (will even cause the flow of traffic to come to a stop to inspect) and always pick out quite a few "offenders" at once. I see them several times a week. They are aggressive and relentless. They work especially hard at rush hours and midday.
