For some crazy reason, every person driving into Decatur High School is being checked for driver's license and insurance.
Which might be an illegal stop. Haven't seen this in years.
Edit: A driver's license checkpoint was held to be illegal recently in State v. Luxon, 230 S.W.23d 440 (Tex. App. - Eastland 2007, no pet.). The fact it is school property does give it an interesting twist.
