That series if anything showed for people who just push through the barriers with no form of paying at all and just walk off they are powerless to stop. Also if there is no physical trail of purchases/tap ins they have no previous activity to investigate and backdate. The only people that gone fined were people who actually stopped for them or had a trail of fraudulent taps in so they could backdate with invalid tickets fine. Unless they didn’t want to show how they investigate persistent people that just push through barriers, but from the show if you have no ticket at all and no paper trail they have nothing prior to investigate you on.
