In game 4 of the NBA Finals, an Anti-Trump Protester ran on the floor while LeBron James was getting ready to shoot a free throw. THe scary thing is that he planned it out and actually shot a video leading up to it, explaining how he was going to do it. He wrote "Trump Sucks" on the front and "LeBron 4 President" on his back. Check out this video on when he was stopped by security: https://vine.co/v/iLujuWQe97r!
Also check out this video from before he started streaking, the event itself, and when he was released after 15 hours in holding. Wow, the scary thing is he is considering doing it again. People really go to great heights to prove a point and make a statement.
