Well as an example, my family and I were riding a Trax train (which is really a nice public transit system) and when we got off, there was a homeless person being pulled off by the police, and she was in tears and obviously very tired and didn't have a ticket.
I offered to buy it for her, I said, "whatever fare she owes, we can certainly pay it." But the officer said "No you can't do that under the law, she is required to buy it herself." But - how CAN she buy it herself in that situation? And why make the poor women feel even worse about herself.
It just made me angry, but Utah is a very restrictive place with a very authoritarian right-wing government, and there is no recourse for fighting back here. I don't blame the police, they know their jobs are on the line also.
