I found this, being shared on a Bruce Lee page, wtf?
This is a video of Gracie Survival Tactics and the description is hilarious:
"The simple truth is, the bad guys are learning. With the explosive growth of MMA around the world, basic submissions, positions, and fight strategies have never been so familiar to everyday people around the world. But unfortunately, when people are learning how to fight on YouTube, or at any of the hole-in-the-wall MMA gyms that are popping up everywhere, they rarely, if ever, learn the moral and philosophical aspects that will ensure the safe and ethical application of the techniques, and this presents a very serious threat to law enforcement professionals around the world "
