If it's hasn't already been mentioned, I think a side by side of the distraught student at Trumps meeting today, contrasted with the tuna taster student laughing hysterically, would be very powerful.
I'm not familiar with the .50 cal, but I did live fire testing years ago with the 20mm galling gun on the tail of the B-52 bomber.
I think the 20mm casing is much fatter than the shell in this image.
