The Act referred to in the article has been on the books since 1980.
As you say, many years ago when children played in the street they were controlled by parents and neighbours and any excessive nuisance was curbed. In short, the children knew where the line was drawn and respected it. If they did not, they had their parents to answer to.
Today the situation is a little different. Many parents (or very often just the one) seem to have little concern what their children do or what effect their behaviour has upon their neighbours. Very often when the children are chastised by people whom they annoy the parents (miraculously) manage to take an interest and side automatically with their children, regardless of the circumstances.
The street is not the place to play football. There are gardens, windows and vehicles to consider. If the children are unfortunate enough to have nowhere suitable to play ball games (and few of them are) then that�s one of life�s lessons that they must learn.
