@Lucy, sometimes an agent's best weapon is her story. It would be rather dangerous for you to get caught with a gun in a country where no guns are allowed, for example. Even if you could prove your agency status, it's going to be quite the trip.
Update on the Louvre Robbery: there are four more being arrested today, unfortunately there's no trace of the jewels being found since October 19th according to BBC News.
You know, there was a question from one of my fb pages I follow that asked, if time travel were possible what event would you visit in history and change. My response was that I'd stop or make sure Hitler were never born. And then I began thinking about it. And thought....how would that change ACME? Would we still be Anerican and international? Would we still have The united nations and NATO?
