An Irish gangster was murdered in front of hundreds of helpless witnesses yesterday during a WBO boxing weigh-in at a Dublin, Ireland hotel, by a hit squad armed with handguns and AK-47s who had no fear of being confronted by lawful concealed carriers, and little fear of encountering armed police.

This is the last known picture of a gangster executed in front of hundreds of boxing fans – as a shocked witness says the gunmen “made sure” he was killed.

David Byrne, 35, was shot dead during a boxing weigh-in at the Regency Hotel in Dublin on Friday afternoon.

Dramatic pictures from the scene show two gunmen dressed as police and armed with AK-47s storming the hotel.

Two different suspected gunmen were also pictured fleeing the scene carrying handguns, with one disguised as a woman.

This picture shows Byrne posing in designer clothes on a motorbike in the Costa del Sol during the past few weeks, the Irish Sun reported. It is thought to be one of the last known images of the notorious gangster before he was murdered on Friday.

The retaliation murder is an escalation of a conflict that started with the murder of a rival gang member hiding in Spain last September. The Irish police (the Garda) are concerned that the brutal public nature of the killing in front of hundreds of witnesses will trigger an all-out gang war.

The Garda thinks that they have identified three of the six assassins already thanks ot photos taken by bystanders, but finding and arresting them may be a whole other issue entirely.

Irish citizens may not own handgun for self-defense, and there are no concealed carry permits in the country, and less than 2,000 legally registered handguns of any kind.  There are 177,000 sporting shotguns and 54,000 registered hunting rifles in Ireland, and authorities think their are another 150,000 unregistered firearms.

If these gangs do go into an open war as some fear, there is little or nothing that the Irish people can do to defend themselves, other than ran and hide.

Note: Boxer Jamie Kavanagh, just weighed in for his fight moments before shots rang out, safely escaped from the scene in his Superman underwear.

Maybe gangster Byrne should have worn a pair.
