PATCO cracked down like that right after starting operation (1968?). As far as I know it nipped the practice right in the bud. I liked the part where the fare-jumper, to save the price of a fare, got picked up on drug charges. Some years ago the NYCTA caught a guy jumping a turnstile, and in accordance with the "broken windows" policy in effect at the time, arrested him, booked him--and got him for several recent burglaries in the neighborhood. They had fingerprints from the burgled apartments but no match in their files. Then, to save a buck, or whatever the fare was at the time, the burglar jumped a turnstile and gave them the fingerprints they were looking for.
