No, what I think most people are getting at is that this perp was accused of a very violent crime and last week was caught trying to bring a shiv into the court room and was not restrained in any way as not to give the jury an impression that he is guilty. That is the PC people are talking about for the most part.
That is probably incomplete information. He has already been tried once on the charge and it ended with a hung jury. Also, is it known what sort of weapon he tried to bring into the court room? Was it assumed that he wasn't trying to smuggle it in but just forgot it?
Of course it turns out that is not the situation in this case. He being removed from his holding cell when he overpowered the deputy and got her gun. Most jails do not allow firearms in the cell area, for just this reason. The "exterior" guards are well armed of course, sometimes with machine guns of one sort or another.
Of course that brings up the question why a single female officer was bringing this scrote over from the holding cell, and not at least two officers, maybe three. He could have been shackled until just before they walked him in to the courtroom, and still not upset the "influence the jury" crowd.
