3 out of the 4 in Derbyshire are in Killamarsh! Does that say something about the problem rather than the solution? It seems to me that these things have got to be better than an exclusion zone or the issuing of ASBOs, which dont work unless they are effectively "policed" and with diminishing funds for such resources or time spent filling in forms a simple digital solution seems admirable.

Is there any evidence to say that they cause damage to hearing – there's plenty of evidence that says ipods and mp3 players do but I dont think there's a plan to ban those.  Ok accepted that there is an argument that says why should every one under 25 be affected by them but conversly why should the majority of people (over 25) have to suffer with the fear and consequences of vandallism etc?
