What authority do you have to counter drones?
The federal government issued this, Interagency Issues Advisory On Use Of Technology To Detect And Mitigate Unmanned Aircraft Systems.
Quoting from a Homeland Security Today article, Multi-Agency Advisory Aims to Clarify Safe and Legal Use of Drone Detection Technology
There is this advice:
"The Advisory has been issued at a time when the commercial demand for UAS detection and mitigation is high, but the authority to use those capabilities is far from clear. To date, Congress has given limited authority to only four federal Departments – Defense, Energy, Justice, and Homeland Security – to engage in UAS detection and mitigation activities, notwithstanding certain otherwise potentially applicable federal criminal laws. The Departments and Agencies issuing the Advisory do not have the authority to approve non-federal public and private use of UAS detection or mitigation capabilities, nor do they conduct legal reviews of commercially available products’ compliance with those laws."
You can't just go intercepting drone aircraft on your own!
