Speeder's Corner

I've been out taking photos of speeders this morning. Might need a tall friend with muscle and a black belt in future.
Two cars turned around and I have had a little altercation with two males. One wanted his photo taken off my camera saying it was an invasion of privacy, I said I'll call PC Chris Pullen on his mobile. The other chap said he wasn't speeding to which I agreed not to put him on.
An interesting tool if not a little unsettling.
Perhaps best If I return to covert mode.
