CHINA: Mr. Tang opens fire in divorce court in Hunan Province killing three judges (discontent with divorce settlement blamed)

HUNAN PROVINCE, CHINA: UK Guardian is reporting that a man known simply as Mr. Tang went ballistic today in Hunan Province, China, killing 3 judges before turning the gun on himself. He was reportedly upset about the divorce judgment (property dispute) from three years prior.
The question I have is, where aren’t there metal detectors in divorce court like there are here in the U.S.? It is absolutely stunning that a litigant was able to get into court and get to the fourth floor of the court while packing a pistol. If nothing else comes out of this, hopefully the authorities will now institute metal detectors in every Chinese court.
What a tragedy. Especially since the judges he killed were not the ones who heard the case.
