As a general rule-if you & 2 other people report them to the rozzers-the Police are obliged to follow it up although this is dependent on whether they've finished their teabreak...

Best way is to make their lives as hard as possible and place obstructions to slow them down.I wouldnt like to see anyone hurt or killed no matter what they've done even when there not supposed to be there,but i do certainly make it harder for them to get upto high speed alongside the river part i walk.

Along the river,they have smashed fences next to the kissing gates and i just plonk big,heavy rocks and logs on the ground cause i know they will have to slow down to an absolute crawl to pass.
