Threat level...
This thing is going to sound like a swarm of bees turned up to 11 in flight. You're not going to be able to sneak up on any terrorists inside of a building with this, nor hide the nature of the drone. They're going to know exactly where and what this thing is.
You know what I'd do? Hide behind a fire door (probably one of the more shotgun-proof things in a building), wait for the thing to come through the doorway, slam the door into it and then grab the barrel and point it upwards. The drone is now at my mercy, and now I have a shotgun. This thing is not battle-ready in the slightest, and I have a hard time thinking how they could make a flying drone in an enclosed space sufficiently resilient.
