Read up on it. Washington is one of 5 states to reject the open fields doctrine. Simply look on line if it is legal to use drones to gather evidence in Washington State. Insurers can do it basically because you have to allow it or they won't insure you, they have that right - kind of implied consent.
I don't need to read up on it.
Thousands of investigative contacts occur daily on private property without warrants.
Now you certainly can tell them to leave...but it doesn't preclude them from knocking..
And I wouldn't worry about drones..
Airplane's are easier anyway.
I was watching that warden show the other day.
They did use airplane's in Michigan to look for bait sites.
Private/public doesn't matter.
I'm just gonna take a guess here,with this law just starting this year.
Majority of tickets ,hunters turning hunters ,will occur during the season. Basically cause the number of people in the woods increase so much. Just a guess.
