Having thankfully never spent any time ‘at Her Majesty’s pleasure’ – or ever even known anyone who has – I’m not sure how much of a problem mobile phones in prison are.
And although I’m pretty sure it won’t be up there with a metal-file-in-a-book, or a sleeping guard with keys dangling from his pocket, it’s enough of a problem for the Scottish Government to introduce new legislation to allow prison management to interfere with wireless signals to prevent inmates from illegally messaging one another or the outside world.
