Express ticket for traffic offence

Response to this request is long overdue. By law, under all circumstances, Uganda Police Force should have responded by now (details). You can complain by requesting an internal review.

Dear Uganda Police Force,

I'd like to know what my options are if a traffic officer wants to give me an express ticket for a traffic offense I have not committed. I was recently stopped by one of the officers within the city center for holding my phone in hand (though I wasn't using it or showing intention to use it) while driving. When, I challenged him that I was not in offense because I was not using the device (as stipulated by traffic offense 22 in the ticket machine) he said that he was going to take me to the station and hand me over to his seniors, which I gladly obliged to owing to my confidence that I was not in wrong. Then as I waited in the car for him to come and we proceed, he returned all of a sudden with a ticket in his hand and "threw" it at me, together with my driving permit (which I had earlier given to him on request), saying "go to court if you do not accept", and he left. I was puzzled at that moment because he did not even ask me to sign against the receipt. The question running in my mind since then is... how could I have defended myself in that situation, or in future confrontations with traffic officers who abuse their work and go around dishing tickets with impunity to unrelenting drivers?

Yours faithfully,
