Chance you are actually able to say that vs. chance you made a mistake in reasoning that conclusion? Still not a bet worth taking.

The at a glance condition is probably the one where you stick a brightly colored piece of plastic in the chamber to act as an unarmed flag. Still best to be careful at all times IMO.
