Eh, a little bit. I've used guns and a sword...well, an energy sword, and I've gotten good with both. I can tell you there's worlds of difference between someone with no skill firing a gun and someone that's been trained in its use. The difference? Someone not trained in using a sword stand a pretty good chance of hurting themselves, but relatively little chance of hurting someone else. People untrained with a gun, on the other hand, usually at least know not to point the thing at themselves, so other people get hurt more often. Is that better? I'm not really sure.
Most people, as a rule, can't be trusted. I learned that the hard way.
No problem. Hopefully you'll be able to get where you're going, but if not, let me know. I might be able to sneak out if you really need a tour guide.
