In fairness, I wonder how far this extends? Can a police officer wear a mourning band, or if in plain clothes, a National Law Enforcement Officer Memorial Fund thin blue line pin? If it involved a foreign national, would anything that depicts an American flag have to be covered up or otherwise disallowed?
What about spectators? Do they have wear attire that is completely lacking in logo so as not to be construed as attempting to sway the jury?
I know from experience that lawyers have complained that there were too many officers present at a trial against a cop killer. The judge just made sure there was a balance of family for the killer and the family/blue family of the deceased.
To be clear, I still believe the BLM is a militant separatist group with a terrorist streak a mile wide.
A Judge is king in his/her courtroom. Do what they say or end up in the pokey for a while.
I know from my own experience that a judge has absolute authority in his courtroom. If he orders an attorney to remove a pin or any other thing he thinks might be prejudicial then she better obey.
Judge could have given her 90 days for contempt if he wanted to.
I searched very briefly and found this: "The Supreme Court let stand a decision that judges can prohibit symbolic political expression in courtrooms, even if it's not disruptive." So the court upheld a judge's discretion but still don't know if its against the law per se.
