Just as a point of contention - my responses were focused on SD outside the home. Once inside your own home, all bets are off and if you've got the capabilities to detonate the claymores on your perimeter and use the malaysian whip covering your front hallway then more power too you. There's no such thing as inappropriate when defending your own home.
Way to go, Hal!
Threegun - you're right. That's why I made a specific attempt to delineate between "suppresive fire" and "spray & pray" in an earlier post. Too many people confuse the two.
