According to this book You can't throw knives as a Girl Scout individual However, the book neglects to mention Uranium, cadavers, and cult rituals
There are many things that are against the Girl Scout rules, but there are also weird activities which the rule book doesn't explicitly say anything about, so you could have a satanic scout troop that makes nuclear reactors and preforms autopsies and it *technically* wouldn't break any Girl Scouting rules.
