SIR - I would like to try and answer the question from Susan Lawn: How to deter these violent pupils' (T&A Letters, May 10).

As a parent of a child at a Bradford upper school, I can say this is a very real problem. Good children, and there are some left, have their learning hindered by disruptive children. Only last week a child assaulted my son's teacher at school.

We urgently need to bring discipline back to schools and society in general. Children naturally try to push boundaries, but now there are none.

The cane was a deterrent; we should bring that back in schools. If the European Human Rights Act limits the use of it, then we should amend or abolish the legislation.

Of course, much of the blame has to be placed on the parents, many of whom have been brought up in the same lawless society as their children, where anything goes'.

I think the government should also take some responsibility; they now fine or imprison parents because they cannot convince' their children to attend school, yet when parents try to discipline their children, the government threatens to prosecute them.
