In somewhere between many and most areas of the US, sgians and weapons associated with battle are legal to carry if you are in national
costume or costume for an event. Not exactly common, but can be done. Bemuses me to find so much objection to this subject here or
anywhere as kilts and military have been so interconnected.

As for weapons in church, I have seen it. Again, not common. I think some feel the ceremonies around weddings and death are for for the
folk attending, no one else, and they'll jolly well do it to suit themselves. Not saying that's correct, just attempting to add a little insight.
