I was DLing some new anime episodes last night like usual but something really f*cked up happened. One of the episodes I downloaded turned out to be some hardcore snuff video. Not just rough sex either, but they beat the sh*t out of this girl and actually slit her throat open at the end. I can't tell if it's fake or not, but it looks pretty real to me. I'm wondering if I should burn it and take it to the police department or something.

Advice?

Note: I will NOT supply a link or any other information concerning the video so don't ask.
