With the state of public school systems in this country the lack of basic biology knowledge is obvious.
It is not even the forensics - it is just a very basic knowledge, that DNA could be samplified from the tissue ( or cells) and it is not shed around like pet's dander and is not identified easily.
They had not been able to reliably identify blood on Trayvon's sweatshirt, which is as much DNA sample as one can get, and some here want to "find DNA on T or Z to prove scuffle". It may support the notion of scuffle if found but if DNA is not found it does not mean there was no scuffle - it is not a negative proof, it is only a positive proof if it exists.
