I will say a prayer for the family. This plays like a bad TV episode of L&O. Not reality! How can a jury member not use a brain cell and say "Okay, so the officer didn't measure with two methods? As a juror, explain to me how the one measurement came up with a result of reckless speed when the driver "wasn't" speeding?" At the least, the jury should have been hung.
When there is smoke, there is fire. I'd have slept easy at night chosing guilty. I'm sure the fact the kid was cited for reckless speeding 3 months later was not allowed in the court, but a good judge would have told the jurors after a guilty verdict that the kid had a history of dangerous driving.
My heart goes out to the family and I wish them peace.
