I know someone who had a store in a local mall
Blacks were about 12% of the customer base but AT LEAST 50% of the shoplifitng (probably a lot more)
She also had to stop taking checks from everyone, because she could not put up a sign saying “no checks from black people” because they ALWAYS bounced and she spent half her time in court, until she gave up.
And when she did take them to court they would threaten her! And when she would win (always) there was no way to make them actually pay.
About 10 years ago, the Minneapolis bus drivers went on strike. The businesses at the Mall of America loved it because their shoplifting plummeted during the strike.
