Hmm, this one strikes me as forced. I mean he wasn’t acting against the current governing body after all, he was acting against a hostile invading force. Defending your goverment from another isn’t sedition. It is war.
And thus, many of the others would fall under wartime acts and not tried in a civilian court, it isn’t murder, it is war, certain casualties are necessary.
Frodo:
Unreported Income (the ring is pretty valuable, you know? and that mithril shirt is “Worth more than the value of the entire Shire”).
Slavery: Kept Gollum tied up and forced him to work as a guide without compensation. This applies to Sam as well, but Sam clearly suffers from Stockholm syndrome to the point that he actually carries his “Master” up an erupting volcano instead of escaping from “servitude.”
Did Frodo get an environmental impact study done before destroying Mt. Doom?
POV
A person might look upon his quest as being part of an illegal war based on manipulated intelligence. Just like LeMay would’ve been charged with war crimes had the USA lost WWII, Frodo would’ve had to face a tribunal after Sauron wins back control of ME (since it had been illegally wrested from him lo these many ages ago).
Wearing body armour is unlawful in some places.
Public posession of a knife with blade length greater than 4 inches.
Disturbing wild animals (that big spider thing)
Wilful destruction of property (the ring).
Oh really? How can you be sure? Is it ever referred to as tobacco? To my knowledge Pippin says, "… The finest weed in all the shire…"
He didn’t say tobacco… 
Impersonating a member of the armed forces (pretending to be an orc soldier) Isn’t that classed as spying and punnishable by death penalty even under the Geneva convention?
Disturbing several endangered species in their natural environment (Shelob, the Balrog, and the water tentacly guy in the lake).
Flying without a license, sure he wasn’t qualified to fly one of them eagles.
i know, that was to stave off the pedants and rabid fanboys
i think all of the other castmembers could be suspected of being Pervy Hobbit-Fanciers, but Sam will kill them if they try anything…
You can argue any of these. But I think the sedition refers more to the scouring of the shire and sedition against Sharky and Lotho the pimple.
Jim
Tolkien talks about it being a relative of Tobacco in his letters. QtM could probably quote the letter.
Jim rabid middle-aged fanboy
Various violation of the Patriot Act, but hell, what doesn’t…?
I’m thinking he would just be held without trial as an enemy combatant.
After all, he was not an agent of any known country…

…and just about the whole cast could sue him for emotional damages. (Especially Seta Soujirou, the poor kid… 
)
I’m pretty sure there wasn’t a lifeguard present in the Dead Marshes, so that’s at least an hour time-out, right there.
I like your moxy!
And the cut of your jib!
Dopers, expand this to any other sc-fi/fant you have ideas on of legality of actions. Written, movie/tv, whatever.
Guess we could always charge him with mopery.
