wait so whats the formula to know if someone is guilty???
saralee, look at the bottom of this screen, run your cursor over it and you will see Newbie FAQ, click on this and look under Accusing (when should I accuse?) there is a lot of helpful info in the Newbie FAQ.
You can also find the formula (and a lot of other help) at http://www.sleuthtips.com/newbies/basicfacts.html
