It would appear from your account that Officer Potter did not abide by
77-7-17:
Like has been said, I'd
love to know more details and quiz you on the specifics, but I've heard over and over again that you should consult an attorney first.
I don't know of many off-hand, but two names I've heard passed around are Mitch Vilos and Greg Skordas. You might start there.
If an attorney ends up being too costly or slow, I'd raise holy hell for Officer Potter. Submit GRAMA requests for all the records related to your encounter, including radio traffic / IM's / emails, police reports, etc. File a complaint with the police department, see if there's a citizen review board you can complain to as well. File a complaint with the DA and AG over the 77-7-17 situation.
And next time somthing like this happens, I'd clam up as soon as it became apparent that it was something more than a friendly, "hi, how are you?" If the prosecutor doesn't drop the disorderly conduct charge soon, then I'd prepare to defend myself in court if I were you. I'd offer to help, but I'm not an attorney.
