I don't think laws are written for the express convienance of the police. Laws like seatbelt, driving cell phone and bicycle helmets are written because too many people think that there are too many stupid people and we need to somehow control them. In the situation described I can't imagine any other outcome regardless of whether the rider was wearing a full length nun's frock. Some would argue that the cop should have written a ticket and by not doing it he was failing to uphold his mandate. I have been pulled over for shooting through a stop sign at night without any front headlight. Once again (I have done similarly reckless things with the same result 6 other times in the last 20 years) I was not given a ticket but they ran my license (each time).
Riding thousands of miles a year in all levels of unshaven and uncleanliness (that was me with the dreadlocks and Peter Tosh t-shirt flying down Grand BLVD in 1989) I have never experienced anything that suggests harrasment.
So is this a ride report or a rant? When cyclists break the law what should the police do? Sounds like the Spokane Police have been pretty cool about not writing tickets. Kudos to them.
