I’m not a fan of folks who come to me with problems. I prefer those who come to me with solutions. In the spirit of that, I offer this idea. If I had a store today, I would require all who enter to leave a name and thumbprint before entering.
I’m not so foolish as to think it would be a fix all. However, it would encourage the criminal types to go somewhere else. If they don’t want to leave a thumbprint, they just might have a reason.
