BTS is an acronym for one of several names: Born to Scheme, Beat the System, Brooklyn Thug Squad, and Brooklyn Terror Squad, mostly. They were a ~100-strong group of ecstasy dealers based in New York City whose tactics involved going to raves, selling ecstasy, robbing other ecstasy dealers and selling their drugs too, breaking into cars, backpacks, handbags, etc. and stealing money, holding up candy ravers, and eventually stabbing people.
I first heard of BTS during the summer of 2000 while talking to a friend of mine from high school over AIM. I had heard that he had gotten into parties so I talked to him about techno and stuff, and he told me he was going down to New York to visit his brother. He asked me if I had ever heard of BTS, and I said no. He told me they were a bunch of people who beat up ravers and break into cars. "they suck!!!" was his exact phrasing, if I remember correctly.
It wasn't until the following January that I heard the term again. I had gone down to Connecticut for my friend's 20th birthday party, and someone called one of his friends asking for directions to the place. After he got off the phone, he was asked who the caller was, to the response of "I don't know." Someone said, "I'll bet you just gave BTS directions to the party, you goober."
I asked what BTS was, remembering the discussion with my high school friend, and they were in fact the same people.
Over the next several months, I put myself on the discussion mailing list for my friend's NYC raver tribe-thingy, and there were several mentions of bad things for which the BTS responsible. By June, an illegal party under the George Washington Bridge had ended with the stabbing of a partygoer by a suspected BTS member. Eventually, a group called BTSwatch was created to disseminate pictures of alleged members.
In June 2001, the group was supposedly dissolved by federal authorities. This is from USA Today (
http://www.usatoday.com/news/nation/2001-05-16-ecstasy-usat.htm): "In June, Drug Enforcement Administration and U.S. Customs agents in New York dismantled a gang that traveled from rave to rave, shaking down suburban kids who were high on Ecstasy. The gang, which called itself the Brooklyn Terror Squad, or BTS, 'terrorized rave parties throughout the Eastern seaboard and in Florida,' says Linda Lacewell, an assistant U.S. attorney in New York. The gang beat up and robbed ravers, stole their drugs and then resold them at the same parties, she says. Ten gang members have pleaded guilty to various drug charges and are awaiting sentencing.
