It’s actually pretty dangerous to be that close to one, and considering that the main island where they live is infested with them, they’re known to ambush large prey in numbers. There is a historical account of them doing exactly that to a group of researchers and killing at least one person at that incident.
I know that reptiles are usually pretty vulnerable and preoccupied during the act of feeding, but a Komodo Dragon is not an animal that I would be watching that closely.
