This is an interesting article how some of the jurors on the El Chapo case had fears when being picked to be on the jury.
I know that case is an extreme example of someone who really does have the power and control to make things happen outside of a prison. He was the guy that had a personal tunnel dug under his cell and escaped in the tunnel on a motorcycle. Obviously arranged tons of outisde help to get that tunnel built.
High profile murder cases just scare me in general because the defendant doesnt have anything to lose if they know they are guilty.
If he thinks the jury has decided guilty already , now he has all weekend to try to lineup someone by phone (or through a visitor visit) to try to stop Monday's verdict day any way he can.
Its very rare that anything would happen but I personally would lock myself in my house all weekend if I was a juror.
