Folks, instead of fantasizing about these things the data is there if you want it. Bank robberies almost NEVER result in a customer getting injured or killed. It is not like they show in the movies. Those are stories for entertainment. It varies from year to year, of course, but as just one example DoJ shows that during a 12-month period there were 7028 bank robberies. In those 7028 only 23 customers were injured, most with minor injuries that did not require off-scene medical treatment. No customers (zero, nad, nyet, zip) were killed.
Armed robbery outside of a bank is similar. Robbers want to get money, not hurt people.
Most banks are open 9am to 5pm. Some an hour earlier or later. Tellers are trained to give the money without resistance. Put a dye pack in it to stain the money. Not much crime in busy places open in daylight. And they do not normally rob “the bank” they rob “a teller”.
Maybe 25 years ago I was reading a news article, perhaps Wall Street Journal, about bank guards. One guard is too easy to surprise and two guards are expensive. I believe it was 15 percent of the time, when a criminal attempted to disarm a guard, the guard was shot. Whether or not he was touching his gun to willingly disarm himself or to draw. Just touching the gun was enough.
Mini Marts and Liquor stores are open after the sun goes down. Some Mini Marts may be open all night long.
The last guy California executed had a Mini Mart (?) clerk lay on the floor and shot him or her in the back with a shotgun. Maybe he was desperate for his next fix. Or the local drug gang was going to kill him if he did not pay for the drugs they gave him to sell? I doubt anyone knows.
Last I read on the issue (1980’s) was an occasional story about some night clerk being fired for resisting a robber. Most big chains do not permit employees to resist robbers or try to catch shoplifters. Cheaper to just raise prices. It is not even news anymore.
Anyway the Mini Marts used to be called Shop and Robs by some police for a good reason. The court decisions that involve them “do” effect us. A lot of them are individually owned.
A friend of my sons was shot (injured) working nights at a pizza restaurant that was being robbed. I stumble on articles about other restaurants being robbed at night. Sometimes hotel clerks. Once a big winner at an auto racetrack was apparently followed down to his motel and robbed at gunpoint. Once a lady that won big in reno was killed and robbed at her first stop in sacramento. A lady that won 10,000 dollars one night at high stakes bingo died in a house fire, presumably after being robbed? Most of us do not even read these things except when they catch your eye by accident.
If any big city put all police calls in newspaper it would be too big for paperboys, too big for news racks. No one would read it.
