Chinese assault rifle? How did he get it back in the US? Remember, all CRATS are above the law. Check with Teddy boy and car in water. We could go on and on, but what is the use.
The articles I've seen did not stste that he brought it back from VN. However, if he did, it would have been easy to crate it up and ship it directly to his new assignment. Recall that he went from VN to NY as an Admiral's aide.
The article doesn't say WHEN he got it. It only says that he owns one. It was probably a thank you gift from the chineese for supporting communism, and being anti-American - a sorta lifetime achievement thing.
