Police One's news story:
Ga. man sues cops, guard over arrest for open carry
The OCer's own words:
Exercising in a public park while armed = "Suspicious"
Illegally thrown out of a park by security for OCing and being rude to security.
Stopped by the police while leaving.
Arrested for trespassing (while detained = not leaving) and jailed overnight.
Seems like everything is on audio.
