Gardai caught me "SPEEDING"

Hey All,

Wonder if anyone can help me, I got stopped by the Gardai for "SPEEDING", I was travelling along about 100kph...max 110kph and a Garda car came flying up behind me pulled me over and informed me they had just pulled me over for speeding at 160-170kph!!!!!!

There was NO WAY IN HELL I was travelling at that speed, I am raging.....I asked him to see the speedgun but they told me that they had followed me and gauged my speed at his collegue was his witness.

There is no way I was doing that speed...they either made a mistake or are rouge Gardai.....He said he was sending out a ticket in the post.....

I don't know what to do....does anyone have any ideas....I told him I was not accepting it and would go to court.......
I don't deserve this **** and feel I shouldn't have to pay for this......
