Not making any excuses for the cop, it appears he was out of line. However, she called once, hung up because she didn’t get a fast answer and called again. The first thing he then hears is her saying “What the *****”. Is it possible he thought this was some sort of prank call?
At any rate, he should be reprimanded, but the poster who suggested he lose everything over this is nuts.
Where are you getting that the girl hung up the phone? The cop hung up on her three times.
