Unmarked cars are there to create cash flow.
If they wanted you to actually slow down their cars would be distinctively marked as a reminder to at least stay close to the limits.
Enriching city coffers is not a proper function of ‘law enforcement’.
I don’t want to increase the budget either but perhaps it’s time for the DMV enforcement and real, live police work to be separated into separate forces.
Expired tags etc are a flimsy pretext for traffic stops, vehicle searches etc and those 2 hr roadsides fishing expeditions mean another 2 hrs a cop is sidelined while burglaries etc continue apace.
