driving to work today north on the 101 coming up on thunderbird a highway patrol vehicle was swerving back and forth through all lanes of the freeway in a "S" pattern slowing down traffic to about 40-45 mph. he did this all the till about union hills. in that 2 exit stretch i passed numerous other highway patrol cars and peoria pd cars. counted atleast 10, and a peoria pd van. at about union hills the truck that had been swerving back and forth just pulled off to the right and let everyone pass him? this made no sense to me at all. also, i have never seen that many cops at one time other than when the super bowl was here. odd?
