Surveillance has never been greater -- are cities markedly less violent than in the past?

(No, urban/city violence is on the rise..[0])

Crime has been on a largely downward trend since the 90s. Yes, there has been a partial reverse since 2020, associated with a general breakdown in norms during Covid. But the broader trend is down.

Please define "the past", because when I'm talking about lifetime trends I don't use 2019 as my baseline.

I think it's very unlikely there will be a statistically significant increase in violent crime conviction rates when these cameras go into action.
