I believe listening is ok (inc. police etc) , but as soon as you act on any information you hear, then you become illegal
one of those stupid laws, like pissing on the back left wheel of a taxi, which apparently is legal (some old law, stemming back to stage coaches or something and was never revoked.....).....maybe I'll try it next saturday night on the sherbet, and I'll let you know how I get on
Anyway, does it really matter, is it going to stop you if it was illegal???
