To be fair, if his claim is "out of control crime" and you interpret it as "out of control crime rates", you're talking about different things. There's enough anecdotal evidence to suggest that in some big cities, the occurrence of certain kinds of crime (like cars being broken into) is up, yet reporting is down, leading to a lower crime rate that doesn't reflect the street-level reality accurately.
Of course, this isn't a problem limited to this domain.
That's too easy to just type; and therefore means nothing. If you think you have an argument, make a claim for what the rates are and show evidence for that. Show evidence that published rates are unusually low.
In the Internet, post-truth era, anecodetal evidence - if you even have that - is less reliable than ever; we swim in oceans of misinformation and disinformation. People post their takes, repeat others, etc. endlessly.
My anecdotal evidence, based on much time spent in cities that are depicted (by right-wing media - let's be honest) as crime ridden, and IME they are almost wonderful, there almost couldn't be a better time to be in them. Crime is low, cities are clean, streets are busy with people and energy, and people go about their days without much of a care. Is that true in every neighborhood? No; but that's not a realistic standard.
