If I blast a mook with the Cain in ME2, I don't shoot the Cain at the same spot again just in case. If I have a massive death-cannon capable of completely annihilating an enemy, then I wouldn't exactly waste my time shooting the same thing twice.

Also, apparently the only "guards" for a location are the ones inside of that location. No one stationed on the exterior of a location who tries to prevent anyone from coming in can be considered a "guard", apparently. Even if one of those people nearly melts your face off when you try to run in the front door.
