You know that more than 5 UPS trucks have been hijacked in the last 5 years so I don't know why you are asking me for such a silly comparison. I have no proof but I would guess amount of people that will [Hijack a UPS truck] < [Shoot down a drone].
@lighybyte
I think UPS truck hijackers are motivated, violent criminals. A couple of dumb teenagers, armed with a potato gun would probably shoot at a drone just for the hell of it + criminals + overly protective property owners
Sure! The comment I replied to, seems to imply that hijacking UPS trucks is a non-existent, or rare event. A simple Google Search seems to indicate that it happens all the time. There for making the original OPs concern somewhat valid.
Your logic is off. If you spend a lot of time around goats then worrying about a goat attack is valid. Similar to how people in North Dakota do not worry about hurricane but people in the Florida Keys do.
