on my way from brynmawr to blaenavon,unmarked ford focus type(think its called a vmax?) dark blue,they had just pulled over a youngster,looked like he was having a ticket

.
the only way you would know is when your behind it there is a very descrete small blue light in the back,you would never know if you were just driving behind it,and because the people carrier type of vehicle you can hardly see the driver-so you wouldnt know there was a copper driving it,
