Depends on your local jurisdictions. Some places have what's called "Shopkeeper's privilege"

Small business tyrany, amirite? I think most places have a policy to let people walk and then use surveillance to build a case over time so they can avoid liability, but the security pukes don't necessarily know that.

Also- exercise extreme caution at Target. Target spends a lot of money on cutting edge surveillance and coordinates with the cops. They'll build a profile and let you walk out with stuff until you trigger the dollar amount for felony charges then set the cops on you.

Fun '2020 George Floyd uprising fact; The Target that was looted and burned in Minneapolis was a laboratory location for testing new surveillance and repression techniques. They worked very closely with the MPD. It wasn't targetted randomly or opportunistically, it was a source of oppression in a mostly PoC community and was destroyed in retribution.
