With cars, you have a license plate that will usually lead you to the owner. Identifying some random person, possibly with a hood, on noisy camera night vision is a lot harder; when you don't have a reasonably small pool of suspects, it's basically impossible.

Even if it would be possible to identify people with a combination of cell phone area warrants and/or by following all cameras around, this level of effort would be far too high (and too invasive) for small crimes like theft and vandalism.
