I feel like I'm not understanding the implications of this, because my reaction is "meh". Can't the FBI fly helicopters now without a warrant? What's different about this compared with past behavior? I guess I'd be more interested to learn what equipment they have on the planes, because that can greatly impact the work they are doing. I'm definitely concerned about drones taking over this work with better tech, but I feel like I should be up in arms about these flights and I'm not.
