I've seen requests for "real evidence," "actual evidence."
What that tells me is the only kind of evidence someone like this will believe is a big handprint of the perp made in the victim's blood on the wall closest to the victim's body, with a signature next to the handprint by the perp, and the words, "I did it!" signed, perp.
Then, because that might not be enough proof, the perp needs to leave their bloody shoes next to the victim, with another note that says, "these are my shoes!" signed, the perp.
Finally, they need a video of the perp either committing the murder itself, or confessing to the murder while grinning evilly at the camera.
Anything else? Not "real evidence," not "actual evidence," and certainly not proof of anything. "Circumstantial Evidence?" Oh that's just not 'real.'
Exactly. And the problem with the video would be it was edited and photoshopped....
