Time to release the photos of the perp as a 12 year old.
All reference to his previous criminal history needs to be scrubbed from the web.
Remove all photos from FB showing the perp holding a gun and flashing gang signs.
The media cannot refer to him as a 20 year old man, he's a victimized teen.
Replace the false flag story: he thought he found a nerf gun and was on his way to get some skittles so he could share them with Mother Theresa.
and introduce a new catch phrase to go with "Hands up, don't shoot."
I suggest, "No, it's not a gun, officer. I'm just happy to see...oh crap! Its a Gun!"
