You honestly believe that there is a peacefull path left at this point? The system is rigged by design, and you are not going to restore democracy in the courtroom.
Quit playing Martin and start playing Malcolm. Pick up a gun and kill your fascist leaders before they kill all of us.
I would solve this problem in the opposite way. Install some much lower barriers(eg 2.5m) which make it painfully apparent that you aren’t going to get anything other than a car under it.
A truck driver isn’t going to keep driving if the barrier is clearly at face height.
