45-7-302. Obstructing peace officer or other public servant. (1) A person commits the offense of obstructing a peace officer or public servant if the person knowingly obstructs, impairs, or hinders the enforcement of the criminal law, the preservation of the peace, or the performance of a governmental function, including service of process.
(2) It is no defense to a prosecution under this section that the peace officer was acting in an illegal manner, provided that the peace officer was acting under the peace officer's official authority.
(3) A person convicted of the offense of obstructing a peace officer or other public servant, including a person serving process, shall be fined not to exceed $500 or be imprisoned in the county jail for a term not to exceed 6 months, or both.
The answer is yes. However, frankly if it played out EXACTLY as you stated, which perhaps your intoxicated state may have colored the story, I don't see how merely asking questions (especially of one who has been STOPPED) qualifies. A lot of these things are nuisance tickets that don't stand up in court anyway. Your friend should at least talk to a lawyer to see how to proceed. There's no point to acquire a criminal record for dumb stuff like this.
Was anybody else arrested or charged with anything?
