Far cheaper than paying for a police helicopter. With quicker deployment, finding people who are lost or don’t want to be found is now efficient and cost effective. I agree with people on the privacy side, but the gains outweigh the loss of privacy. Besides, if I am committing a criminal act within my house, in-person video surveillance or drone surveillance is NOT going to see that unless you take your activity out into plain sight of the public. Which for any surveillance for a private investigator or criminal investigator is the same, Free game when you come outside.
