Don't see why they'd be charging...
If everyone knew about it, there'd be a lot of death if everyone follows the killing spree idea...
If just I knew about it, I'd go on a mad rampage of preaching on International TV that it was going to end and sex, drugs and crime. Then, a minute before it ended, I could say,
"Told you so."
I think I would want to enjoy myself, although not sure why for so many that involves killing. Although I guess I could understand theft. For a short time I would aim to have the greatest art collection in the world! Loved ones would figure in there somewhere as well. Feasting, merry making and reflection and so forth.
