You can’t fix stupid
Anyone robbing a bank these days is likely to get a bag full of dye packs and remote beacons. It is one of dumber types of dumb robberies.
Still, most robbers hit multi-branches before they get caught. Probably by staying to branches that dont get hit often and aren’t prepared. Average takes are less than 2K, last I heard. My robber got 2 years in Fed prision for his trouble.
