No matter how you look at it

Nothing good can come from assuming a tactical type posture with a firearm on a public street in the situation that the OP described. Mall Ninja wannabe stuff.

It's perfectly legal to carry into Wal-Mart or Target, but dontcha think the coppers'd string ya up for walkin in with yer scatter gun?

Or maybe lit up.
