I've enjoyed the courthouse theme of this thread because I spend a lot of time in courthouses. I'm a trial lawyer, and my local courthouse has such a strict no weapons policy that I finally had to take the Gerber micro LST off my keychain. I used to leave my keychain with the bailiffs, but once I left the courthouse distracted after 5:00 pm and walked back to my office, only to discover that I had forgotten to retrieve my keys and was now locked out of both office and car. I had to lurk outside the judge's entrance until one exited and authorized the bailiffs to let me in to reclaim my keys. I've seen them take Leatherman Micras, SAKs, everything.
We had a bad courthouse shooting several years ago in a rural county. It happened during a divorce hearing --family law cases are the most dangerous, just as domestic disturbances are the most dangerous calls for police officers. The hearing was held in the judge's chambers. The husband drew a handgun on his wife across the table. Her attorney, a fine young lawyer and family man, shielded his client with his body and was killed by the first shot. The husband's attorney and the wife were able to get out the door and escape but the gunman was between the judge and the door. The judge locked himself in the bathroom but the husband fired through the door, killing the judge. The he chased his wife up some stairs and out onto the roof of the courthouse, where he shot and wounded her.
The sheriff was walking into the courthouse when he heard shots and saw the husband on the roof, standing over his wife, berating her and threatening to kill her. The sheriff took aim with his handgun and hit the gunman in the neck, wounding him and ending the incident.
After that, security was tightened in most Florida courthouses, but not all. In some rural areas things are still casual.
This incident was memorable for a number of things. First, the tragedy of a man feeling so much hatred for someone he had loved enough to marry that he wanted to kill her. Second, the sacrifice of the attorney who protected his client at the loss of his own life. And third, the sheriff made an outstanding shot!
