At this late date in the Age of Celebrity Scandal, how is that stars keep allowing their friends to videotape them engaging in illicit activities?

We don't blame Miley Cyrus for indulging in a bongload of whatever she's depicted ingesting in the video posted by TMZ earlier today. (The Age of Celebrity Scandal doesn't pay for itself, people.)

But we definitely have to wonder why she didn't tell her pal with the camera to shut it off before lighting up.
