My local paper shop has one of these, great it is. Whereas you had to barge through small groups of hoodies on the door they are nowhere to be seen because if anybody starts hanging about outside he simply switches the device on and they do one. But now these campagners come along (no doubt someone who doesnt live in an area affected by youth disorder) calling for their bans.
