Should intelligence agencies gain powers to tap phones and hack computers?

AI-generated summary, admin reviewed: This law gave intelligence agencies new surveillance powers when investigating serious threats such as terrorism, espionage, weapons proliferation or attacks on critical infrastructure. The measures included tapping telephones, entering computer systems and secretly listening inside private rooms. They could be used only when a concrete serious threat existed and after a multi-stage approval process. Supporters argued that intelligence agencies needed modern tools to prevent attacks and respond to changing technology. Opponents feared excessive intrusion into privacy, insufficient oversight and the collection of information about people who were not suspected of wrongdoing. Swiss voters approved the law.
