Two things - 1, they were processed and released to their mother immediately, so they are not "hostages", so maybe histrionics are not called for with regard to that? Just a thought. 2, from reports that are coming out, they, along with their father told the police ahead of time what they were going to do, and they did it with EMPTY CUPS. IT was symbolic, i.e. a media ploy. Nothing more.
The fact remains that they were even detained in the first place. They commited no crime, Greer is the criminal.
