I think you'd have to do a crime of international proportions to warrant being tried by the International Tribunal in the Hague. Something like being the leader of a warparty involved in slaughtering innocent civilians or such. But knowing you I guess that idea shouldn't be completely discarded.
Anyway. Say you didn't like some guy named Marty. And you'd put a rifle somewhere you know Marty is going to be facing at where he will be standing. And that rifle has a string attached to the trigger. The string is led to where Marty would be through an ingenious system of pulleys, all of which is clearly visible. At the end of the string is a note that says "Marty, don't pull this string". Now say Marty saw all that and then decided to pull the string anyway and got his head blown off. Who killed Marty? Did you kill him or did he kill himself?
