Does How You React to a C&A Report Affect the Outcome?

I've had my doubts/suspicions about certain players being multis but never bothered to file a C&A report against them because I honestly figured they would be too shifty to get caught. I thought back to instances where players would come up with a story(true or fabricated?) about how it was all just a big misunderstanding and they were simply housemates, brothers, etc..
My point is that couldn't any person caught with multiple accounts use the "flatmate" excuse or the "ignorance plea" regarding sitting if they were convincing enough? A lot of multi accounts get busted because they deny it and of course when the evidence is provided it's an open and shut case but those accounts that come up with an excuse that wouldn't fool a 4th grade schoolteacher, they get off the hook.
I suppose I might start a suggestion regarding a way to prevent a person with a good story having a better chance of beating a C&A than a person who pleads the 5th, ect, but those types of suggestions tend to be flooded by cronies of the people who have gotten away with this sort of thing and show an arguably falsely negative response. It seems to me like a no-brainer that if you're flatmates/brothers using the same IP that you would check with CC before you start logging from the same computer, not after you get accused of being a multi, especially if the veteran person sharing the computer is all too familiar with the site's policy on multis.
