Fighting vandalism in the near future

When we have the "internet of things" and ubiquitous sensors, here's one small use that would warm my heart: anti-vandalism.

Consider graffiti:

First of all, spray paint cans won't operate on any surface if you don't have the owner's permission.

If some young punk somehow manages to start to tag some graffiti, his identity is captured, and he hears, by name, that he is being fined.

On second offense, not only is the fine multiplied, but a swarm of paint drones tag swatches of his hair, his body, his clothes, his bag, and his ride.

Etc.
