The local Dyer police hide everywhere and anywhere. No radar or similar, the officer just gives his estimate of your speed. I went to the city court for 37 in a 25 (guilty but extenuating circumstances that didn’t matter to the officer or the court) and there were over 40 people in a back room of City Hall for the same by the same officer. It seems everyone does 37 in a 25 and all the cases I saw were handled by paying court costs of almost $100 with nothing added to your driving record.
