Most every night, the news programs show yet another “smash and grab” robbery of the various retail chain stores. It has gotten so bad that a number of Walgreens, Walmart, and other stores have ceased operation in the very high crime areas of San Francisco, Seattle, New York, and other cities that have decided to abandon the rule of law, defund the police, and implement a no money bail for those that “might” be arrested. Local government help for these retailers is unlikely. Let me propose an option that would help reduce theft greatly.
Do it like Costco. That is, a customer membership card is required for entry to the store.
