You need to lay off the FUD! The reason these are installed generally has nothing to do with crime (outside parking enforcement at most). It’s done for marketing and tracking purposes. Brick and mortar stores are desperate for the kind of data that online retailers have access to about customers and the folks making the purchasing decisions generally don’t have the first clue about privacy implications.
Source: I worked for a company doing something vaguely similar (we covered the inside of stores, not the parking lot). I spent my time there working to provide best in class anonymization to only allow aggregate data.
As to your specific fear mongering questions:
> If a car shows up that is registered to someone on a warrant for a violent crime, should the mall owner do nothing? Not their business?
1) that data isn’t generally publicly available to them
2) that’s why you hire security guards
> What about a car registered to someone who lost their license due to DUI? What if that person frequents the mall and kills someone with their car?
1) again, not generally publicly available
2) what makes you think the drivers licenseless person could be the only driver
