While I cringe at the casualness of calling this guy Goofball, I do like the idea of using goofy nicknames for premeditated killers, as suggested by Rod Cockerham:

Blockquote 1. Ladle 2. Teeter 3. Bowl 4. Cloud 5. Pouty 6. ■■■■■ 7. Crotch 8. Ferrule 9. Pudge 10. Smear 11. Pimple.
Most of these goofballs would much rather be known as a thug or otherwise scary person. I imagine that most cops who do unjustified shootings would also rather be thought of as a badass than a goofball.
ETA: What is boing boing’s problem with moisture? Seems like a goofball word to auto censor (in quote above)
