The LANDED Act establishes a federal framework allowing state and local law enforcement agencies to acquire, deploy, and operate counter-unmanned aircraft systems (counter-UAS) to detect and mitigate threats posed by drones. The bill requires the Department of Homeland Security, in coordination with the FAA and Department of Justice, to create an application and approval process for state agencies to use counter-UAS technology, with detailed agreements specifying authorized equipment, operational conditions, and safety protocols. State law enforcement personnel may intercept drone communications, disrupt control, seize aircraft, and use reasonable force to disable drones when responding to credible threats to public safety, national security, or critical infrastructure. The bill includes mandatory post-event reporting, periodic federal oversight, and provisions to ensure counter-UAS operations do not interfere with civilian communications networks.
