I have helicopters fly over my house all the time. I must live near a helipad or something. Anyways yesterday I had a police/search and rescue helicopter fly over very low to the ground. The only reason I'm worried about this is a have a couple of my babies outside near the timberline. Do the police need a warrant to fly over your house to look for plants? and if they already had a warrant wouldn't they just knock on my door?
