At least in my neck of the woods, large mall parking lots and WalMarts enjoy the most crime and that translates to the highest percentage of CCW holders being involved. If you pull up the crime map, you can actually guess the WalMart locations pretty accurately.
The suburb of Denver I live in had a few officer involved shootings between 2009 and 2018, then in 2019, we had more than those previous 9 years combined, what changed? We got a new Huge WalMart. About half of the gun related incidents ended up starting or stopping at, you guessed it, that new WalMart. A few months ago, in a span of 7 days, there were three shootings, one between the criminals and police, combined with two home invasions, a car jacking and an attempted abduction of a young woman. Two of those involved lockdowns of at risk facilities in my zip code. The few large mall parking lots are also crime magnets for drug sales, vehicle thefts and break-ins.
Go to your city or county and search for the crime stats. Most have a crime map and you can search by crime type as well as find the photos and addresses of registered sex offenders, halfway houses, etc. That should give you local information to help you decide what places might be better to avoid.
Yeah, then DITTO Ed4032's comment.
