A proposal once called the “Rave Act” to crack down on dance parties where illegal drugs are sold soon will become federal law. It was slipped into the “Amber alert” bill by Delaware Senator Joseph Biden, who has been pushing it for the last year, the Los Angeles Times reports. Civil libertarians object. Formally named the Illicit Drug Non-Proliferation Act, the bill’s aim is “to deter illicit drug use and protect kids,” Biden says. Rep. Barney Frank (D-Mass.) voted against the broader crime bill to protest Biden’s provision, which never was voted on as a separate measure in either house of Congress. The new measure amends a 1986 law that holds owners of crack houses responsible for allowing their property to be used by drug makers or dealers. Now federal law will be expanded to include properties used or rented for one-time events. Penalties could include prison, civil fines of $250,000, or twice the gross revenue of an event.
