I'm not sure this is a bad thing. I thought police routinely used private camera accesses willfully provided to them. If that camera is watching a public area, with no reasonable expectation of privacy, it seems hard to argue against.

What this plan does do, to what I assume is already routine, is force them, to respond to and investigate crimes they observer incidentally, when doing so.

I can imagine the hyperbolic situation, where cops watching video 24/7, hoping to score a big exciting drug bust to score free skimmed drugs a money, then a big payout to their department from forfeitures, and praise for the politically positive and public bust.....then they get 'stuck' helping some lady getting raped instead, costing their department resources and money and not give the cops free drugs at all. That has to be a bummer for cops.
