Certain people here are taking our comments far too seriously!
For starters, nobody got hurt. If someone had gotten hurt, well, I'm sure my comments would've been different. Then again, none of us was there, so we don't really know all the details.
For me, it just seems odd that someone like that would be allowed into the Hall. Imagine the conversation the Elders would have with him at the door:
Samurai Dude: "Hi, I'd like to take up that free Bible Study offer please. Let me in."
Elder: "Oh, sure, hehe, nobody's ever done that, please excuse my incredulous expression and sh*t-eating grin. Normally we almost have to bludgeon people into accepting Bible Studies with Armageddon-death threats involving small, brightly coloured birds. Wow. Speaking of bludgeoning, why on Earth are you carrying around a 60-centimeter scimitar?"
Samurai Dude: "It's for my packed lunch. We haven't got any knives at my workplace."
Elder: "Oh, silly me, why didn't I think of that! Please come inside, Brother! One last thing. We have a very strict dress code in this Kingdom Hall, and I'm afraid I absolutely can't allow you inside if you're wearing a dress."
Samurai Dude: "This ain't a dress! It's a sarong! All Samurai wear them!"
Elder: "For that matter, we can't allow any man wearing a head-covering in, either. The other Brothers would be severely traumatized, sense of male chauvinism shattered and so forth, if they saw a man wearing a head covering. It would be a terrible thing to Witness!"
Samurai Dude: "Fine, fine, I'll take off the turban."
Elder: "You know, minus the turban you really do look like a fine, upstanding Brother. We can tolerate a dress and a sword, but that turban was really too much. Welcome inside."
Samurai Dude: <ASIAN ACCENT> "YOU DISRESPECT MY FATHER! DIE, SON OF DOG! DIE DIE DIE! NEEEEEEEEEEEYAH!"
Well, that's how I imagined it, anyway...
