Why do you think dna evidence is so important in many court cases? what changes has it made to forensic science?

This is a thing thats part of the last answer*

Yes it is important cause if you find some guys DNA on a gun or such he is more then likely your killer. And it can prove different theories and open new possibility's. And it helps scientist and others to understand who where and what happened. 

Hope this helps ;)
