I question whether Milwaukee and Chicago are outstanding examples. I looked at a few reputable sources and those cities nor their states seem to be extremes in terms of car theft rates. Most of these law enforcement agencies are not specifically breaking our carjacking.
Random presentation of car theft stats comparing Chicago to a handful of others. We hear a lot about Chicago because many have a vested interest in deflecting discussions about crime. When was the last time you heard about the insane motor vehicle theft rate of Dallas? https://public.tableau.com/shared/W2KZH4JC7?:display_count=y...
