i'm not sure if you guys read the actual decision by the court, but here's the link http://www.supremecourt.ohio.gov/rod/docs/pdf/0/2010/2010-Ohio-2420.pdf the case (by the city) is a mess and should've been tossed. no wonder this guy took it as far as he did. officer says defendant was going 70mph per visual radar reads 81mph (a full 11mph off) officer COULD NOT produce his cert on the radar (which should've been a dismissal right then) court then said, ah, well, the ticket will be revised to show the 70mph. defendant fights this for obvious reasons appeals court says, sure, why not charge a guy for something, and when you can't prove that, charge him for something else after the fact even though his training was ALREADY suspect (ie, not having certs and a discrepancy of 11mph between visual and radar). supreme court says, well, even though you correctly cited at least 1 court ruling where visual estimate is not enough, there are other rulings that said it is, so there. the 1 dissenting justice said that the officers credibility needs to be decided by jury.
