Son: I killed that man.  Here's video tape to prove it. You can clearly see my face, and you can clearly see me putting the gun to his head and pulling the trigger.  Here are the clothes that I wore that night.  Covered in the dead guy's blood and powder residue from this gun, which I will also give you.

Father: He's totes innocent. The evidence proves nothing. It's just a witch hunt.

Son: I'm actually a witch.  So's my Dad.  

Father: WITCH HUNT!
