What they do want from us is local reporting. So if its listed as south london then a londoner. If we did that we could probably get more action than some random bloke from worcestershire calling bout a car he thinks isn't right in london.
If we had people in say each county that were informed and they took up the investigation so to speak. Certainly those in sheffield,essex and birmingham(there seems to be a little rise in thefts in that area) might want to do that.
We don't want people risking themselves so get to the point of knowing address,contact details and some evidence, contact local police by dialling 101, talk to vehicular crime coppers, maybe even go with police to view. They'll soon be educated.
Just a thought....
