Colorado lawmakers are scrambling to find agreement on a bill to limit drone surveillance. Several efforts to create the state’s first legal parameters for drone usage have fallen short this year. But one measure pending in the Senate may survive. The bill would allow civil penalties for drone surveillance in areas where people have an expectation of privacy. The limit wouldn’t apply to law enforcement or other government employees. Senators amended the bill so that violating someone’s privacy with a drone would be a civil offense, not a crime. Private investigators and the Colorado Press Association both argued that the criminal penalty could discourage legal investigations and news gathering. The bill now awaits action by the full Senate.
