I don't think the threat is internal though - not from their citizens. Its external groups - basically, pirates. I don't see how weapons laws will protect them against pirates. Indeed in their FAQ they allude to the fact that citizens will have to be armed to resist the more amateur pirates. More serious operations they hope to resist through not having enough worth taking. That is a more dubious line of argument but in either case I don't see how having or not having weapons laws will really protect them.
