That is not restraint, incidentally. It is training and it is entirely mechanical.
You do not interrupt because every interruption tells the other side which sentence hurt, and because a judge is watching two people and forming a view about both of them, and because a woman who sits still while she is described is a much harder thing to explain away than a woman who objects.
I sat there for nineteen minutes with my hands on two folders and let a man tell a courtroom I was unstable.
