This is from a few pages back but can I say I've never even heard anyone say this before about irish people! I'm Irish myself, (I live in Glasgow hence my keen interest in this case) and I always use my cards instead of cash because it means I can keep track of all my spending using online banking and I feel I'm more likely to get robbed/lose money carrying around wads of cash. It might be the way some people are brought up to use cash but it certainly isn't a cultural thing.
As for people wondering how the police found out he bought a barrel, the first thing the police would do when they traced AP was get his phone records which would show that he drove to a B&Q on the sunday.
