About once a month Livermore PD decides they want to extort money from college students, so they run a 3-motorcycle speed trap where they pull over college students heading to Las Positas Junior College. They have printers connected to their radar systems so they can issue tickets as fast as possible and pull over a maximum number of students. This is definitely a revenue generating move because there are guaranteed to be students hurrying to class and lots of potential victims. Outside of school hours (8am-5pm) M-F, though, there are rarely cops here.
