What?
I'm making a simplistic point about the '80-100' ambiguity, obviously it wasn't simple enough....
The police officer, with his calibrated speedometer, gave a testimony stating that he followed the OP over 0.5miles doing between 80-100mph in a 50mph zone. And you think he could have "walked away from it" if he had a decent solicitor. lol ok.
Again, easily picked apart by a decent Brief, I like how you added 'with his calibrated speedometer' yourself though, you can actually prove this can you, with full documentation? You know, like a Court would need to prove guilt.
The point is: Never admit to anything. EVER. If they want to PROVE you did something wrong then let them work for it, this is where they come unstuck. Admitting anything is just crazy (Even if they do have you bang to rights).
