Mine is the one from Little Rock Arkansas (Season 6) where a female dressed in a postal uniform got arrested for aggravated assault with a deadly weapon on her boyfriend because he has abused her before and she went off the deep end and threatened him with a gun, then she screams at her boyfriend he's dead and then he's gonna kill herself, she also told the police not to let him get her out because she's gonna kill him.
I also liked the episode from Atlanta (Season 11) where a woman got arrested for fleeing and eluding a police officer, when the officers ask her how much has she been drinking she said nothing, she had a Snickers bar, she also claims that she's half dead.
Another episode I liked where a female got arrested was the one from Palm Beach County, Florida (Season 11) where an intoxicated woman was drinking beer on someone else's property, when she was told to leave she refuses, then when the officer tells her that he's gonna arrest her for trespassing if she refuses to leave, the woman's response was "Oh go to Hell and trespass!" That's when the officer decides to put her under arrest, she then starts resisting arrest and took a couple swings at the officer, when the officer tells her that she needs to calm down, the suspect's response was "you go to Hell and tell me to calm down! You'll never calm me down in your own g-damn Hell!"
I really admired the way Kenneth Voiret handled the situation with this woman, I wish he appeared on the Season 14 and 16 episodes, he seems like a really chilled officer, I like that he treats every person with respect.
