Have you ever thrown rocks at a law enforcement officer?

The unfortunate and tragic death of a 15 year old boy at the US/Mexican border in El Paso made me wonder about his behavior as well as the Border Patrol Agents reaction. I’ve never thrown rocks, large or small at anyone let alone someone armed with a gun. I have been hit with a thrown rock and I can vouch that it isn’t a pleasant feeling. Considering they still stone people to death in some backward countries I’m sure it could even be deadly.
