Drone

Drones Can find people and save them if they're in danger.  They Can also find people and kill them and they wouldn't even know that it would hit them.  But when it comes to drones there are a bunch of what ifs.  

What if Obama was on a airplane and a  drone was guarding it.  If the drone malfunctioned and thought that the plain that obama was in was a target?  I'm not educated enough to judge drones and that is something I need to look into.
