So in every crime scene in recorded history the perp leaves behind evidence of themselves?

The general concensus amongst forensic experts is "YES". I watched a trial in which the defense counsel got the prosecution expert to admit this. The defense council then asked if there was any physical evidence tying the defendant to the crime scene and the answer was "NO". Case over!!
