As you probably gathered from my profile, forensics is not my field. &nbsp;Therefore, I was unable to make any useful observations concerning either the science or the math in this article -- but I assume that's not what you hired me for. &nbsp;The article is very well written, but I made a few small changes here and there.<br /><br />If you are pleased with my work, please consider rating me -- every good rating helps.<br /><br />J.
