I knew a real nice fellow. A head teller at the bank. He was in charge of counting the money when it arrived on the armored truck. One week the shipment was short $20.00. He reported the discrepancy. No big deal. A few weeks later, he got another shipment. He reported $20.00 short again. He got 5 years in prison.
The first week the bank had intentionally shorted the shipment. The second time they didn't. They had videotape of the cash being counted, sealed in a bag, the camera followed the bag into the truck and stayed rolling until the truck arrived at the branch. The cameras on the bank branch recorded the driver unloading the bag, walking into the branch, and handing it off to the teller.
A real nice guy. College educated. Young wife. Young kids. Bank embezzlement. At least it was federal time.
