Just don't work the Northside. Honestly, very little trouble happens on the southside, never had an ounce of trouble from any punter going south.
I haven't encountered any serious issues working the northside, I was just letting my mind wander... although I think one of our colleagues/competitors was caught in the crossfire in Finglas a while back.
Anywaysanall, gang warfare isn't restricted to the northside, there have been plenty of shootings both sides of the Liffey. In fact the greatest concentration is probably in the city centre itself. I have noticed that I seem to carrying more punters that I'd suspect to be criminals since we got the PUC back from mytaxi and I increased my reliance on it.
Taximen carrying guns (sometimes overtly) is quite common in other jurisdictions with high rates of gang related crime e.g. Moscow, New York, etc...
