If an FBI agent posed as a witch doctor, and I paid him to cast a death hex on somebody, do you seriously suppose I'd be brought to trial? Give it up, mate. This isn't Burundi.

Find an undercover cop, and pay him a few grand to off someone with a voodoo rite. See if you go to jail.

Oh, you might be locked up--for your own protection. And then put under psychiatric observation. But there's no way such a person would ever be prosecuted for attempted murder. Not as long as he only asks you to cast a spell. If he throws in a request for, say, a curare=tipped blowdart, all bets are off...:)
