Here is a 1984 view of the Louisiana electric chair, from the witness room. What surprises me is how close the witnesses sit. I realize it must be the same for the lethal injection — I had thought witnesses chairs would be elevated, as in a theatre, and further away — but I see this supposition was baseless.
I am guessing this is one of the reasons why witnesses are traumatized, watching murder up close and grisly murders of people they know at that.
Axé.
