I know what u mean i have many a people in the shop saying kids have been bullied there or an insident happen.
Many complained about drinking taking place there too especially at night.
Its great to have a descent park but on the other hand i feel it was built in the wrong place too close to the school and shop and out the way of public view And i knew there would be problems, there is c.c.t.v but i'm aware there are no tapes for the video so whats the point in having c.c.t.v?and who actually checks the c.c.t.v?
The only suggestion i have is be there when your kids are at the park but thats not always possible and impractical.
