It can be hard to determine what's fake news and what's real news, especially if you don't have the time to track down sources. That being said, let me give you a little tip. If your news is coming from text on an image, or a meme, then it's fake news. Real news doesn't come in that format. I don't see esteemed journalists in their offices putting that stuff together.
Immediate red flags come up when looking at this Facebook post that claims a recent school shooting wasn't reported because an armed citizen shot the shooter before he could hurt anyone. The implication is that the liberal news doesn't want to further the "good guy with a gun" narrative. Too bad the only part that's true is that there was a man with a gun... who ended up killing himself.
