The D.C. Council has unanimously passed a strongly worded bill to deal with an animal rights group that has been known to wear masks and appear unannounced outside District residents' homes shouting things like "You should die." Residents have been complaining to their council members that they felt "terrorized." Critics of the bill say it's too broad and limits First Amendment rights.

"They scared some people so much that they feel like prisoners in their own homes," said Ward 3 Councilwoman Mary Cheh, who sponsored the Residential Tranquility Act of 2010.

Police can be called, Cheh said, but they don't always have the legal grounds to arrest the protesters.
