Typically, in products liability litigation, the product involved in the accident can be an eloquent “witness” as to what happened.

The product tells trained eyes much about what happened in the mishap via “positive” evidence, i.e., the appearance of damage, dents, marks, scratches, and so on, or via “negative” evidence, i.e., the absence of damage or marks that should have been there had a particular event or sequence actually occurred.
