While he was living, I don’t think his bullets were most likely to go through another human, but I do believe he was living on a boat because he had to flee Belize (I think?) because we was wanted for murder and couldn’t return to the US because he was wanted for various things there, too (probably including that murder because it was an American).
His advice is only relevant here because his name is on the software, not because he was a good role model. Fascinating guy, but not one to look up to.
