Need help from the PF legal team! This is the story from the top....

I was driving home monday, came to a junction which turned into a street with houses on one side and a dry stone wall on another, parked cars on the one side so in effect a single lane.

As I turned into the street a car the other side of the parked cars flashed me through, so not to hold the guy up I gave it some gas and carried on, about 100yds further on, a copper was in the middle of the road waving for me to pull over. So I pulled over and he starts giving me grief about driving like a cock. Fair enough, pointless trying to argue with the knob - hes already made up his mind!

So in the back of the car, fills in the usual producer and then says hes reporting me for driving without due care & attn. Pretty pissed to say the least but had no chance but to just nod and agree.

I received a generic letter friday telling me that im being prosocuted for dangerous driving and not due care & attn. So the bastard has gone and changed the 'charge'.

Now, from what I know, this is the scenario

1 - the exhaust is loudish and he heard that
2 - he didnt really have a clear view of my car
3 - he was on his own while another officer was getting his dinner from the kebab shop he was standing outside of at the time.
4 - he cautioned me in the back of the car for due care & attn and now its changed to dangerous driving.

Where do I stand, anyone know of any good solicitors in the Cardiff area?

Cheers
