You can do the same thing without cops more cheaply in the long run. Just raising the crosswalks to sidewalk height completely changes driver behavior, as it's both a speed bump, and it's clearly communicated that the crosswalk is the pedestrians' territory that the driver is crossing through.
We can deal with most of these issue through design rather than a threat of fines.
As a headsup, pedestrian deaths at crossings is consistently higher in places where right on red is legal. It's not bad drivers, it's a bad law enabling bad driving.
