I had this sent to me by several readers.
In that 2005 incident, Chrisman and his partner arrested a homeless woman on an outstanding warrant. According to the internal affairs investigation, Chrisman and his partner planted drug paraphernalia on the woman -- because they wanted to play a joke on the woman, who is mentally challenged.
Take a look at the video -- Chrisman puts a brilo pad and pipe in his partner's left hand. His female partner then pretends to pull the pipe out of the woman's dress.
Chrisman said he knew the suspect, and just wanted to get a rise out of her. He was suspended for one day and put on the Brady List -- his partner was also suspended for one day and put on the Brady List.
The woman wasn't charged with anything related to the planted evidence.
Video at the link.
It is hard to find the humor in planting evidence on a mentally-challenged homeless woman, though my guess is this became a joke only after the video appeared.
No matter what the officer's explanation, the disturbing fact is that Phoenix police officers seem to carry on their person, as part of their equipment, throw-down drug paraphernalia. Why is no one asking why Chrisman had the crack pipe in the first place, or how his team was so well trained that they could wordlessly set up the plant. This whole episode smacks of something well-practiced.
