The sympathy for the guy here is comic.
Lets deal with some facts.
This nut managed to cause traffic problems all through central Dublin, at a time where businesses are struggling to survive, leading to many of the main bus routes being delayed, people late for work, companies who need staff in at particular times to function having their staff delayed, whole also affecting deliveries in the city. Acceptable? No.
His antics came close to injuring a guard outside the gate who was doing nothing other than his job, and had to jump out of the way, according to the witnesses. Acceptable? No.
He tried to attack gardaí who sought to get him down of the rig with a hurley according to witnesses. Is that OK? No.
To complain about Anglo Irish and its cost the idiot cost the state money at a time when it is broke. Dumb? Yes.
He was also damn lucky. If anyone tried to drive a large vehicle up to the gates of most parliaments around the world they would have been shot dead before they got near it because they would have had no idea if the vehicle was loaded with explosives. The Oireachtas is always protected, and has been since 1922, by armed military police. He was lucky none of them opened fire.
What he may have done is curtailed the right to protest of all citizens. Technically it always has been illegal to gather outside the Oireachtas for security reasons. But the law has never been enforced. Just as that nut who attacked the referee in Croke Park meant that no crowds will ever again be allowed onto the pitch there, so this as*hole is likely to at a minimum lead to new and expensive security arrangements being put in place. At worst, it could lead to the enforcement of the ban on people gathering outside the Dáil. Hopefully that won't be the case, but it may well be one of the things that will be considered alongside new security arrangements.
So all because of some clown, Dublin's ability to function this morning was disrupted, businesses already on a knife-edge lost more money, the safety of guards was endangered, and new and expensive new security arrangements may well be put in place.
I hope they throw the book at him.
