"Crap" said John Phoenix when it became clear that the animals did not understand DNA.
John Pheonix turned around and pulled out his phone and connected it to his mobile internet provider and called a friend of his uncle.
"Hello, Luke Triton, I need you to come to the forest with your school books!"
Luke came to the forest with a book about forensic science.
Luke understood animal language so he was able to teach the animals about forensics including DNA.
The animals went "aaaaah!"
The animals now understood John Phoenix's arguments and he was acquitted.
THE END.
