Yes, I know there are really tears there. So how can I say they're fake? Come on. You've never heard of method acting? How do you think those people in dramas produce the tears? They're "real" too, but they have nothing to do with any sort of real emotion. They're either so deep in character that they're got themselves momentarily convinced the emotion is real, or they're method acting, which means they're reaching back to some sort of real tear-jerker from their life to produce the tears.
If you really think this fraud is upset about the kids, well, then you were probably gullible enough to think he'd heal the planet too. If the shootings make him genuinely mad, it's not because the people got killed. It's because Congress didn't just up and give him what he wanted in response to it. It's always about him, and here it's about getting you to remark on his show of emotion - not to pressure Congress to pass something because he's not asking for that, but rather to shame Congress into forcing poor upset Obama to resort to executive orders, which Rob already told you will do nothing.
