(Image: Collins Photo Agency)A young man who stabbed a drunk intruder to death has been jailed for three-and-a-half years. Jack Power, the intruder, was killed after being stabbed by Dean Kerrie.Ireland’s Central Criminal Court heard that Power had been drinking until the early hours before breaking into Kerrie’s home.He is understood to have seen damage to his car which he believed had been caused by Dean.Power used a rock to smash the front window of the Kerrie home and then entered through the front door.Mr Justice Paul McDermott said Power assaulted Kerrie in his bedroom.There was also a suggestion he attacked Kerrie’s mother, according to the Irish Mirror.Kerrie was 17 at the time of the incident and is now 21.He found a knife in his room and stabbed Power, who was older and taller though unarmed.The court rules that while Kerrie was legally entitled to use force in defence of himself, his family and his home, the force he did use was ‘grossly’ excessive.READ MORE: Three dead in Spain shootout horror after armed police swoop in Dean Kerrie.

The Oireachtas [Parliament] has recognised the special position of those obliged to defend themselves or their property from unlawful attack, particularly in their home. That is therefore a matter that has to be taken into account when considering the culpability of the accused.’Those who are attacked in the home are entitled to use force and sometimes lethal force in defence of themselves and their home.’
