I can think of a few practical difficulties myself.
eg
Who is actually flying the thing

It flys itself.

and how do they know where to go?

The person who needs it says where its needed.

Must they keep it in sight?

Nope, because it flys itself.

What happens if it loses it's control/video signal[behind a building say]?

It isn't controlled by anyone, it flys itself.

Sounds like someone's got a toy and
trying to justify/find a use for it.

Then you need to get those ears tested, BAD.
