Submission + - California Gov Brown Vetoes Bill Requiring Warrants for Drone Surveillance (latimes.com)
"This bill prohibits law enforcement from using a drone without obtaining a search warrant, except in limited circumstances," the governor said in his veto message(PDF). "There are undoubtedly circumstances where a warrant is appropriate. The bill's exceptions, however, appear to be too narrow and could impose requirements beyond what is required by either the 4th Amendment or the privacy provisions in the California Constitution."
At least 10 other states require the police to get a court warrant to surveil with a drone. Those states include Florida, Idaho, Illinois, Indiana, Iowa, Montana, Oregon, Tennessee, Utah, and Wisconsin.
California's drone bill is not draconian. It includes exceptions for emergency situations, search-and-rescue efforts, traffic first responders, and inspection of wildfires. It allows other public agencies to use drones for other purposes—just not law enforcement.
