Jaysus that sounds a bit paranoid Murt!

Just because your paranoid doesn’t mean they aren’t out to get you
There are loads of areas in Dublin that I would not knowingly enter in the late afternoon, evening or especially after dark.
Just because your abroad on holiday in a foreign country doesn't make a place any safer. By your dress and actions you will stand out as a tourist and are therefore more vulnerable. Every big city has these areas.
For some weird reason which I cannot fathom at all, I always seem to find myself in the local fish market when I'm abroad. It's like an inbuilt homing sensor, or maybe these places all have many fish markets. I don't know
