That's the stupidometer on my plotometer after the last episode of Breaking Bad.
OK, you've just extracted a damming confession from the most dangerous drug criminal in the SouthWest. So naturally, you, one other lightly armed guy, and the only good witness go out to arrest him. You don't call for backup, even though he's not going anywhere. You make the bust, and who do you call, in the presence of aforesaid gangster? Your idiot wife.
Next, two carloads of suspicious characters show up. Now do call for backup? Of course not.
