Cell Phones
Inspired by this post on the we'll be looking at the issue of mobile phones in prisons. Prisoners aren't allowed phones in jail for good reason: mobiles have been used to deal drugs, continue to run criminal activities, and plot escapes.

Add to that a report which spoke of an "apparently limitless" supply of mobile phones in , and while there have been recent attempts to bring technology to bear on the issue, clearly there is a continuing problem.
There are technical aspects to this too: we know it's possible to jam phones, we know it's possible to track phones and to detect cell phone transmissions, so why is it difficult to stop prisoners using them in jails? We'll try to find some of the answers Saturday.

The demand for personal (and larger) jammers was reported in many papers -I saw it in the Guardian, but here's one I've just googled from the Telegreaph:-
