Like most fellow Iowans, Crystal Knight was intoxicated at 2:45 AM Saturday.

However, Knight, 26, made the mistake of haranguing cops who arrived to break up a physical altercation on a downtown Iowa City street. Knight, cops reported, “immediately began screaming at the top of her lungs and continued with abusive rhetoric. She showed signs of intoxication.”

Still, police allowed Knight (seen above) to leave the scene.

But Knight continued to scream obscenities as she walked away. As a result, she was subsequently arrested, prompting a new high-decibel attack.

If Knight thought cops might give her a second second chance, she killed that possibility by telling one officer, “You bitch ass, broke ass, 21 Jump Street rookie ass punk.”

The cop surely realized that Knight’s cutting pop culture cite was more a reference to Jonah Hill than Johnny Depp.

Knight, whose rap sheet includes arrests for assault, theft, and driving while barred, was arrested for public intoxication.
