John Ramsey served in the Phillipines when he was a naval officer. He also visited Bangkok.
So did I. In fact, I don't a single flying officer at either Bien Hoa, Tan Son Nhut or Phan Rang who did not take the opportunity to grab a hop to Bangkok. Most went for some better food, others merely sightseeing and almost all to purchase a 9mm pistol and ammo. The issue sidearm to flight crews was universally disfavored, actually, it was junk. What relation does John Ramsey having gone to Bangkok bear to today's arrest or the murder?
