Should police be allowed to restrict people suspected of posing a terrorist threat?

AI-generated summary, admin reviewed: This vote concerned preventive police powers against people considered to pose a terrorist threat, even when they had not committed an offence. Authorities could impose reporting duties, contact, location and travel bans and, in the most serious cases, court-approved house arrest. Supporters argued that police needed tools to stop attacks before they happened. Opponents argued that the definition of a terrorist threat was too broad and that restrictions based on predicted future behaviour threatened due process, human rights and children's rights. Swiss voters approved the law.
