It's rather humorous that the power strip and extension cord issue, that started this whole controversy, is now a moot point. They are allowed as long as they are not frayed or damaged. No mention of labeling them in your luggage or other B.S.. It really hasn't changed. If you're irresponsible enough to bring a defective, frayed or spliced device onboard then you deserve to have it confiscated.
I read the firearms point as being "Firearms" and as an example "i.e." they list starter pistols and non-operating guns as examples. Not just exclusive to these two things but all Firearms. Dang, I was hoping to bring the Citori over/under with me on my next cruise and do a little trap shooting off my balcony.
