Seriously, I rarely go to concerts much any more, and I’m much older than Riley Cooper and even I know that at a concert, the one thing there is going to be plenty of, are cell phone cameras! As a public figure, you have to know those are out there, that people will recognize you, and try to grab photos and/or videos of you, and if you’re going to drink too much and get stupid, it’s going to wind up on YouTube.
It’s not fair, it’s not nice, but it is what it is. Just look at what is happening to Manziel. Same thing, everyone knows photos of him drinking or doing something else that might be considered news is going to get attention.
If you don’t like it, you could always go work in a factory or an office. When the rest of us act the fool, it might still end up on YouTube, but no one will care.
