Ted,
that's a great idea.

Actually, all of this has to do with installers trying their informed damnedest to do the safe thing, and customers understanding that if something goes wrong for some reason, they are jackholes if they even THINK of suing the A/V installer who had nothing to do with the actual problem, just happened to have safely changed a power cord.

We still have to think about this stuff to be sure that what we do, we do consciously. Instead of "I just cut the power cord...." Any explanation that starts with "I just" is a bit suspect as it avoids going into detail and is exactly what an uninformed person would do when doing something unsafe.
