Before the bill was passed in February, there was nothing stopping Law enforcement from using drones for surveillance without a search warrant. That's changed now, with several exceptions including border patrol, emergencies, and training.
There was also no regulation on the type of force that could be used by drones - they're now limited to non-lethal tactics like TASERs and tear gas.
While the Grand Forks Sheriff's Department has the use of drones, there are none owned or used by law enforcement in the Fargo area.
