Copwriter,
I can't help noticing that all of your, "... and then I arrested him after he challeged me" stories involve people who deserved arrest - they were publicly inebriated or were already suspects in a crime. I've never in my life been in either of those unfortunate situations.
If I hadn't done anything to be arrestable, you bet I'd refuse to answer questions. Anything I say can only get me into a worse place than I start if I start out lacking justification for arrest. Actually, I never said I'd actually *say* "Arrest me or leave me the hell alone." I said that was my motto, mostly developed as a result of the warrantless and unjustifiable searches of my body by the TSA. To an officer, I'd be respectful but still not answer any questions other than name, rank and serial number.
