Reality Television.

An acquitance told me about her appearance as a witness on one of those courtroom shows that run on daytime tv.

Since she had witnessed an altercation in a church parking lot, she was conscripted into testifying. However, she was flown accross country to do so before a national television audience.

In the preshow prep, she was instructed to interrupt anyone testifying falsely in her opinion. Generally, this is considered poor form in a conventional trial, but in television "reality", it makes for really good conflict and is apparently encouraged.

Your Honor--"She's lying"!
