We've seen plenty of stories over the past few years about prisoners getting contraband mobile phones -- even to the point that many prisons have been asking for exemptions against mobile phone jammers. However, here's a new one: a former prisoner in the UK is suing the prison system for destroying the contraband phone they discovered he had. He claims that the phone should have been just taken and kept in storage, but instead, it was used to train dogs, who chewed it up. Perhaps the rules governing the UK prison system are a bit different, but it's difficult to see how any prison system should be expected to hang onto contraband for the prisoners until after they're released. No word on how he got the phone in the first place, but perhaps it was specially trained carrier pigeons (or not).
