I'm sorry to have to say this, but there won't be any bloodshed. When the swat team is lined up at the door, they will open it and hopefully, they have hidden the "unlawful" guns where they can't be found.
I'll bet there is a lot of PVC pipe being sold in that state.
I'm sure you are familiar with the phrase "When you think it’s time to bury your guns, it’s really time to dig them up."?
