You're speaking to the wrong crowd Al... You're using a carpenter's analogy with a drywaller crowd..Peter,
Just discussing, if a mistake is made once every 15 years, considering all the Funny Cars that make runs do you see it as an epidemic?
I think that there are more pressing matters to address. I know this isn't the perfect metaphor but, If a carpenter hits his thumb and breaks it it doesn't take a new policy for the other carpenters to not hit their thumbs. All the others just automatically pay more attention.
Hell, as soon as one drywaller gets drunk.. - the rest fall over themselves to join in... ..
