THE corresponent of April 13 may be right, perhaps parents should be made respondsible in some way.

I feel, however, a return to stop and search might be more useful. Anyone found with a knife should be immediately put in a cell.

Nevermind the useless instant fine, or the opportunity to give a false address.

Put them in front of the magistrates in the morning (the US seems to be able to do this).

Give them a term of imprisonment, or a large fine payable before release.

It's worth a try and can't be more useless than what we have now NAME AND ADDRESS SUPPLIED.
