Sentinel! duh... I forgot about them two. You never know where the bodies could be stolen from... just as long as a really big media fuss would be made over the absent corpse so when it reappears the media would show up exactly where it was found!
Also, allowing the body to be embalmed will make sure the tissue stays intact and is less likely to be ravaged by pests, rodents and vultures.
but, a total side plunnie, couldn't you just see Kaito get tugged up on stage and then outshine the magician at a revue in Reno or Las Vegas? I'd love to see Kaito's respose to the Star Trek experience... snicker. Or the DooDah parade! yee gods... having them run across the wierdest of the wierd festivals in USA would just be viscious. But, I still want to try some of the garlic ice cream at that one CA festival!
One of the greatest things about the US is just how wierd we allow our freedom of expression to get... snicker.
