No this isnt a joke ! Travelling into Bristol yesterday and i noticed a mobile camera van up ahead, which in itself it getting normal. but parked in front of the van were two police cars, which i thought was a bit excessive. another 50 yrds down the road were two police motorcycles with riders eating what can only be described as "coffee and doughnuts" and then another 50 yrds down was a final police car. Surely the van and one car or bike to stop you would be sufficient !!
