It doesn't take much time to investigate property crime. They don't even both to take the video footage from the cars. Just ask on any Tesla forum where all the cars have a motion activated security cameras. They could spend 5 minutes to take the screen cap of the person and send it out to all the officer and community.

A victimless crime at the checkpoint, yes - but many people driving drunk end up in accidents and endanger public safety.

As for the real issue here: it's a problem only if there is not enough police to simultaneously conduct sobriety checkpoints and prevent crimes against property at the same time.

Fix police education, payment and staff and the problem is solved without pitting different dangers to society against each other. Or, even better, provide adequate public transport to allow people to have a drink without having to rely on driving drunk to get home...
