If that was the case, you wouldn’t expect property crime like motor vehicle theft to follow a similar trend, but it does. A very large chunk of the crime is gang related, and there is no gang violence in the suburb I live in.
Bars are also disbursed all over not just in the city center. We have bars here, and they produce essentially zero crime.
But even if all of the crime was alcohol related, all of the crime isn’t occurring inside bars.
