A Conservative MP said homeowners should be allowed to arm themselves with Taser guns yesterday after his house was burgled while his family was asleep.
Thieves used David Davies' Fiat Punto as a getaway car when they made off with a bag containing £300 and the family's passports early on Sunday morning.
Mr Davies, the MP and Welsh Assembly member for Monmouth, was asleep upstairs with wife Aliz, 27, daughter Sophie, two, and three-month-old son Dominic.
The burglar alarm was turned off because his sister-in-law and her boyfriend were sleeping downstairs at the semi-detached house in the village of Osbaston, South Wales.
The raid meant Mrs Davies was not able to take the children to Hungary the following day where her father was hoping to see his grandson for the first time. Mr Davies, who has called for tougher sentencing of criminals, said constraints on people trying to defend their homes were "crazy".
"I feel devastated and violated. It's an absolute disaster," he said. "It's quite disturbing, especially when it happens in the way it did with young children sleeping upstairs.
"I'm left wondering what would have happened if we had found them, which we could easily have done."
He said training people to use electronic stun guns would prevent cases such as that of farmer Tony Martin who shot a 16-year-old intruder dead on his property in Norfolk.
"Why shouldn't responsible householders be allowed to carry a Taser if they have been trained to use it?"
Police later discovered the abandoned burnt-out shell of the W-reg Fiat, he added.
