Yes, absolutely, using a laser to aim the shotgun makes it possible to be highly accurate shooting it from the hip, or from your little toe!
Seriously, it is a great tool.
I use a Crimson Trace laser grip on my EDC precisely for this purpose.
But, of course, using a laser dot would definitely be "aiming" it no simply spraying and praying from the hip.
I'd be much less sure of simply relying on a flashlight beam.
