While not condoning the violence, it would be interesting to know:
Of the 100 or so Romanians how many of the adults are actually in work.
How many of them are children and so are in receipt of child benefit (the parents) and local schooling.
If the houses they live in are rented privately, or provided (paid for) by the council.
How many people actually live in each house.
If the crime level has gone up since they arrived (petty crime, burglary, begging and so on).
Finally, are the Romanians net contributors to the community, or do they cost the local community money.
These may seem petty questions, but in times of high unemployment, people being laid off, companies going bankrupt, people losing their homes, tax levels increasing, why should the local people in Ireland pay for total strangers from the other side of Europe to come there and cost them money.
Just because a group of idiots in the EU decided Romania could join the EU and let anybody from any EU country live anywhere else in Europe.
What a totally stupid idea.
