The Supreme Court avoided a catastrophic accident last year when a piece of marble at least two feet long crashed to the ground in an interior courtyard used by the justices and their aides. That's according to several Supreme Court employees. The incident has not been acknowledged publicly. It took place in the spring of 2022, as the court already was dealing with death threats and other security concerns before the justices overturned Roe v. Wade. No one was injured when the marble fell. The employees say Justice Elena Kagan and her law clerks had been in the courtyard earlier in the day. They say the piece of marble was big enough to have seriously injured someone.
