Yes, one would think so.....I have read about some very unusual experiments done by sleuthers that are trying to figure out how physical injuries occurred, or clothing appeared a certain way.
If the hoodie is half zipped and suppose the hood is pulled down to restrain the arms, what prevents anyone from simply stretching the fabric in whatever way is necessary to have arm movement? Wouldn't the zipper simply unzip more, or the fabric stretch and tear ... especially in a life or death situation?
