Even more "scary" is the fact that the visiting muja band were traveling on expired visas. The INS has no idea where these men are now.
If you read the link to the Washington Times article - clue: it's located two posts above yours - you can find the reason why "the INS has no idea where these men are now" - every one of them left the United States between July 10 and July 20. The INS isn't supposed to keep a track of people once they've left the country. Musicians came. Musicians played. Musicians left. It just keeps getting scarier all the time, doesn't it?
