Brothers Artwork

So upon our very first visit to Wishon Lake. There came a time where all three of my younger siblings got bored, to which my mother suggested they draw on construction paper. I have no idea what was going through my brothers' head, but to our surprise we saw this. When we inquired about his artwork he said it was him shooting his baby brother. I am a bit concerned that someday years in the future, I or my mother will be on Nightline with someone questioning us if there were any signs. To those circumstances I should hide this drawing, I guess too late.
