Its all on facebook now with witness accnts . So if i was you id stop your threats as you could well be getting a knock at the door as some may see this as a form of defending such a person
Strong comments just because theres no video lets wait and see what the police say if hes innocent he has nothing to worry about, why follow a child if you dont mean them any harm !!
Just checked DVLA website - the car is UNTAXED - and therefore UNINSURED - so have reported it as such!
Hope he gets a huge fine! - I can't stand selfish idiots like this - if you spot an untaxed car - please report it here- https://forms.dft.gov.uk/report-an-untaxed-vehicle/
