Your greatest danger is a tip-off.
ALL of our greatest danger is going to be these drones: http://www.infowars.com/drones-shot-down-over-texas-video-goes-viral/
(Sorry, I saw this with the dudes shooting the drones down and needed to share!)
Though I believe the admissability of arial evidence is in question due to the case of Dow Chemical v. US. http://scholar.google.com/scholar_case?case=2807189437219807369&hl=en&as_sdt=2,29
A tip-off still needs an affidavit before a warrant is issued, which most peeps(i.e. your neighbors) don't want to sign their name to. Even then, a warrant needs to expressly specify with exacting certain terms what the agents are looking for and can confiscate. If the specifications of the warrant are not exact, there tends to be grounds for the case to be dismissed. But, of course, the damage is done by then to the stiller (i.e. his equipment is gone or damaged, as is his reputation).
