If an individual is determined to expose innocents to a deadly, communicable disease, then the authorities are duty bound to quarantine him.
The ACLU needs to pound sand.
Fair enough, but at least let there be some sort of court order so that the guy has the ability to challenge it. We are talking about the government here. Are you really confident that if you were quarantined that the government would make a point of letting you out as soon as possible? That you would be treated properly while detained, etc? I am not objecting to his being quarantined. I am objecting to the government having the power to detain you indefinitely on the whim of a bureaucrat.
