They turn up mob handed at stations and on trams in the daytime when it's fairly quiet to catch fare dodgers. Travel at night and you rarely see them. Occasionally you do see a few travel safe security onboard. I did read somewhere that they've either stopped or are stopping these because the yobs see them as a challenge, meaning Joe public are on their own. Blackpool trams still have conductors onboard.
At the moment trams and stations are just too easily accessible, so attract gangs of youths, homeless and random drunk/drugged up loons which make your journey absolute hell if you're unlucky enough to encounter them.
