Two days ago, I was riding along at the speed limit (NY) on an Interstate highway when a police officer came up behind me, pulled into the passing lane slightly ahead of me, then dropped back and turned his lights on. I pulled over and he asked for my license and registration, which I provided. My bike also has a current, valid inspection sticker and I handed over my insurance card. IOWs, completely legal motorcycle in good condition ridden by a guy wearing a full-face helmet, protective jacket, gloves, riding pants and motorcycle boots pulled over for no discernable reason. The officer was polite. He told me that his automatic plate reader submitted my plate number to the system and came back with no verification that it was a legitimate plate number. When that happened, he asked "dispatch" to enter the number manually, and again, there was no match. Now, I know the plate number is in the system at DMV because for the past five years I have renewed my registration on-line. Also, there is a 'stack' of registration stickers on the plate where each year I placed the new sticker over the old as is the approved practice. Before taking my papers to the cruiser, where he again ran the plate number, he felt the plate and said that novelty plates can be purchased. Again, the numbers did not match, but he was convinced my bike was properly registered and insured, blamed the state computer system and told me to go. We exchanged a few pleasant sentences including that I was running a day late because I'd been holed up in a motel ill for a day. Still not at the top of my game from the illness, I put my papers away and went on my way. My questions: If being perfectly legal is not enough to prevent being pulled over, then what is? Was the officer justified in pulling me over? Does this happen on occasion to other motorists? If this is not an isolated incident, what does this mean to presumption of innocence, Fourth amendment rights, and civil liberties in general? https://en.wikipedia.org/wiki/Fourth_Amendment_to_the_United_States_Constitution "The Fourth Amendment (Amendment IV) to the United States Constitution is part of the Bill of Rights. It prohibits unreasonable searches and seizures." EDIT: Lastly, should I just drop this or seek a court fight to protect others? The above is a rhetorical question. There is NO WAY I plan or would even consider spending time or money on a quixotic legal battle. As we've all seen, there are those readers who consider every statement literally. Hopefully, this edit will keep them from stroking out.
