It sounds like your point is that people should be willing to give up their privacy in return for the chance of detecting (not preventing) violent crimes.
I think it's also disingenuous (or at best, completely naive) to pretend like harm from Flock and other surveillance is hypothetical/theoretical. Here are just 2 recent examples of REAL harm:

You can guarantee that there are many more that haven't been caught.
