I am not an expert in law but suffice to say i have had my share of being arrested etc in my younger days. I have been in similar situations where you give the car a bit of gun and out of nowhere pops the bacon crew. Firstly never nod,gesture or agree with anything the pigs say, the least you say the better and try to keep it to a bare minimum ie: just whats required name address etc. it is hard for me to comment on your situation because i was not there but if you are being charged i would suggest you visit a solicitor at the earliest opportunity. not to worry you but speaking through experience if you go not guilty and go to court, if you get found guilty the penalty is worse than if you had put your hands up for it in the first place. someone told me once never go not guilty on driving offences but that was a pig so get yourself to a solicitor asap
