A former Fianna Fáil councillor has received a six-month suspended sentence and fined €800 for being drunk and a danger, being threatening, abusive, or insulting, and carrying a knife.
Gary O'Flynn, 37, of Hayfield Drive, Castle Court, Whitechurch, Co Cork, had pleaded not guilty to all three charges, but was convicted last month.
Judge Olann Kelleher said the night in question was a very dangerous, fraught night for all the people involved.
He said the message had to go out that people who carry knives can expect a prison sentence.
However, he accepted O'Flynn was a man of previous good character, had no previous convictions and has shown remorse.
He sentenced him to six months in prison for possessing a knife, suspending it for a period of two years on good behaviour.
The judge fined him a total of €800 on the two other public order charges.
During the trial, the court heard how the charges arose out of an incident at Gorby's Nightclub in February 2011.
The club owner, Niall Carney, had approached O'Flynn following a complaint that he had thrown a drink over a woman.
Mr Carney said O'Flynn became aggressive and swore at him.
He refused to move to a quieter part of the club and warned the club owner he was a practising solicitor.
Gardaí who called to the club described O'Flynn as very abusive and one garda said that in all his 40 years in the force, the defendent was the most arrogant man he had ever met.
The court was told that when O’Flynn was asked about a pen knife found in a pocket after his arrest, he said it was for his own protection and he would use it again.
