I didn't ask about wa law. Can you cite any law in any state that requires me, a private citizen, to assist law enforcement against my will?
I can't cite, but, I have come across a few states where a citizen is required to assist a cop at the cops request/demand. Memory is pretty foggy, but I have this vague impression it was to help apprehend a criminal.
And, while it is an absurd statutory demand, it makes sense in a perverted sort of way--meaning its too easy to predict when you think about it. One of the declared reasons for a militia is to put down insurrections and so forth.
Mark Twain tells a humorous story along these lines. Twenty years after the War Against Southern Independence shut down riverboat traffic on the Mississippi River, ruining his career as a river boat pilot, Twain decided to take a trip down the Mississippi for old time's sake. In St. Louis he met a fella who catapulted him back twenty years to an event in Twain's life. Twenty years earlier, Twain had been called upon as militia to put down large riots in St. Louis. He was marching in column to the riot scene when he decided he didn't want to participate. He handed his rifle to the fella beside him, saying he was thirsty and wanted to just get a drink. Of course, he never went back. Twenty years later, at the beginning of his trip down the Mississippi he spoke to stranger. That stranger then asked him, "So, did you ever get that drink?" All in a flash it came back to Twain. This was the guy to whom Twain had handed his rifle all those years ago. Twain responded something along the lines that he couldn't remember, but he'd be glad to buy the fellow a drink now.
While a humorous little story, it shows how citizens can be compelled to contribute to law enforcement. I think even the Federalist Papers, or maybe Framer writings, mention the militia being called upon to put down insurrections and enforce the law. So, if government claims the power to call out the militia for law enforcement, its only a small illogical step (on government's part) to commanding citizens to help cops.
I realize the foregoing is pretty indefinite, but I just cannot recall the cites.
