"There are llamas loose on the M50." I thought Seán O'Rourke would burst a blood vessel trying not to laugh on the News at One on Thursday. Llamas 'on the lam'. It wasn't quite "there's a moose loose aboot the hoose" but it was close.

Several hours later, the Cab (Criminal Alpacas Bureau) had rounded up the fugitive camelids. The Corpo appropriated them, valued them at €5,000 and the Australian Circus Sydney had to stump up or they were going to be sold on. It was a kind of ‘Llama Nama’.

This was a perfect allegory for the week: a circus being held to ransom by clowns.

Down on O'Connell Street, protesting taxi drivers caused traffic misery in a bid to get the regulator's attention. I have a certain amount of sympathy for taximen, but not when they use us as hostages.

On Monday we had representatives of the public sector holding us to ransom over pay – at the ultimate expense of those on welfare. On Tuesday we had a farcical, raucous debate on RTé about Lisbon – both sides blackmailing us with various threats.

Along with this we had the resignation of the Fás board and yet more revelations about our politicians' expenses. 'Mé Féin' was ringmaster at Big Top Ireland and every selfish act it introduced bolstered the proposition that we're not fit to govern ourselves. We've given the country over to solipsistic jerks in the Dáil and on the ranks. Thick-skinned bullies who believe that we are here merely to do their bidding.

By Thursday evening, I had reached saturation point. Self-interest tedium had set in. I was no longer shocked or angry by selfish unions or taximen or TDs – just exasperated. You probably were too. This is a natural response to information overload. It happened with the Troubles in the North. Each report of an atrocity drew less of a response.

When I read that banker Seán FitzPatrick is entitled to free flights with Aer Lingus while having €106m in loans, I filed it under 'Nothing Would Surprise Me Anymore' and moved on.

Then, just as I was unfurling my white flag, up popped P Bartholomew Ahern TD. My knuckles whitened. On Tuesday, Bertie chaired a debate on Lisbon at the UCD Law Society where he declared himself 'neutral'. He wouldn't be taking any questions. (Bertie doesn't like questions.)

The following day, the first signs that the man who blew the boom is successfully reinventing himself appeared. The Indo gave him a soft ride in a playful report about the debate. It didn't question why a disgraced taoiseach would be so warmly welcomed by our future lawyers.

The Irish Times noted that he drew a tiny demo over fees outside the hall, while, inside, the students cheered him to the rafters. These are the same law students who will sign on as soon as they graduate, thanks to Ahern's policies.

How can we have forgotten so soon? Bertie has been hiding in plain sight since cocking up the economy. He has been walking around in his own solipsistic bubble, impervious to our anger. He knew that all he had to do was ride out the storm and eventually he would be home and dry. The public and the media would get tired of being angry with him. He was right.

Bertie brazened his way through a tribunal that nearly had to hold him upside down and shake him for answers. He told us he won money on horses and our jaws clattered on the floor. And here he was, reconstituted as elder statesman, wearing his old Teflon suit and smug grin. In any other country (bar, maybe, Libya) he would be hounded out of public life. In Ireland, he is asked to be an honest broker at debates.

Last week, Brian Lenihan said he was determined to punish those who had undermined the state. John Gormley also said that FitzPatrick would be made to pay back all his loans. A jaded public arched its eyebrow. It doesn't take a genius to see they were playing to the gallery. How can we believe that FitzPatrick will feel the consequences of his actions while Ahern is still giving us two fingers?

If Lenihan is really serious about dealing with economic wrongdoers, he could look to the Treason Act of 1939. This defines treachery in terms of warfare, but could be amended to punish those who, through financial mismanagement or wilful profiteering, threaten the survival of the state.

Such an amendment would make it easier for justice to be applied in the case of fallen politicians and bankers. Under such a definition of treachery Bertie Ahern and his Old Boys Club would be traitors. They should be punished as such.

We can complain about Siptu or taximen, but until we have made Ahern and his ilk accountable for the destruction of our economy, we can't expect them to behave in a more civic-minded fashion. 'Monkey see, monkey do', etc.

I started this column with a play on words about llamas and Nama. Here's another one: what's the difference between Nama and Bertie Ahern?

One deals with loss-making toxic assets – the other is a toxic ass that won't get lost.

Some day we might make him pay. I'm not holding my breath though.
