The citizen review board, headed by yours truly, has determined that the driver broke no known policies or laws, and therefore acted lawfully and appropriately.
There is no law against stretching your legs and picking up your cane in the presence of a police officer. Not even the catch-all of 'resisting' would apply. He was within his rights the whole time.
I know it seems obvious to cops, and to people who read about cops every day. WE know there are these unwritten rules about how to increase your odds of survival during police encounters. Not everybody knows though. And they aren't real rules.
lawfully and inappropriately are not one in the same. The man's actions were lawful, but inappropriate. It is lawful to wear a "Pre-Teens are Sexy" t-shirt while driving a white van through a school parking lot, but if you're concerned about you safety while being around a number of fathers who might see this, it would also be deemed inappropriate.
