There have been a few in Kilkenny with joint Gardai Customs and Social welfare targeting markets in Cillin Hill and the car boot sale. A few years ago.
I think it is a bit heavy handed to be honest. The guy who was telling me about it had a mortgage of around €1600 per month and a young family and was doing his best to try to keep his house. He has lost his house since.
It wasn't the checkpoint that caused him to lose his house, but it's more or less survival for some of the people being targeted.
