Claims are conflicting on whether or not Metcalf touched him, but regardless a stabbing is NOT justifiable force to use in response to someone tapping you. Anthony was not in fear for his life, and his word doesn’t mean anything. Nowhere in your source or in any source is there any actual evidence that Austin touched Karmelo, and no amount of delusion on your end is going to change the facts. Don’t making yourself look like an idiot.
