This question for people who work in criminal forensics?

Does anyone know where I can get some supporting evidence


That a 3 inch blade cant make a wound 6 inches deep in someone's rib area?This question for people who work in criminal forensics?
Due to tissue compression, a small knife can make larger wounds than the length of its blade. The elastic nature of tissues causes them to tend to return to their original positions leaving a large wound cavity. Lenny Magill constructed a ';meat-man'; to simulate a person and demonstrated how a small box cutter could make massive wounds.This question for people who work in criminal forensics?
Park your Cadillac in a Cracker Jack box....same rationale!





The blade can only go three inches deep...no deeper in depth than the length of the knife blade.





If the handle were three inches long along with the three inch blade...and the knife was pushed ALL the way in to the end of the handle...then I suppose it could be possible.
okay i am no person who works in law or any thing but i am an emo kid no a 3 inch blade can not cut a 6 inch wound deep in to any part of any were on any thing why would u need evidence tell them 2 put 2and 2 together
Why would you need evidence of this? Isn't it kind of obvious?
