he gave you the texting ticket because he was trying to be nice..he probably knew it didnt have as much merit as the speeding one but he was trying to do a favor. he probably didnt think you would try and get out of it, seeing as he cut you some slack. IMHO i think its rude that you want to try and get out of it when the whole point was to not give you a bigger fine and however many points on your license. trying to get out of the entire think is kind of ridiculous.
sorry if my post came off as harsh, just my honest opinion
