As if there weren’t enough:

If union protesters turn violent — as they increasingly have — can you trust pro-union police to intervene?

As he says, always bring a camera. Actually, you should follow many of the Marine rules for a gun fight at events like this when it comes to cameras:

1. Bring a camera. Preferably, bring at least two cameras. Bring all of your friends who have cameras.

2. Anything worth shooting is worth shooting twice. Memory is cheap. Your reputation is expensive.

3. If your shooting stance is good, you’re probably not moving fast enough nor using cover correctly.

4. Move away from your subject. Distance is your friend. (Lateral and diagonal movement are preferred.)

5. If you can choose what to bring to a demonstration, bring a long lens and a friend with a long lens.

6. In ten years nobody will remember the details of megapixels, stance, or tactics. They will only remember whose picture was taken.

7. If you are not shooting, you should be communicating, reloading, and running.

8. Accuracy is relative: most demonstration shooting standards will be more dependent on “pucker factor” than the inherent accuracy of the camera.

9. Use a camera that works EVERY TIME.

10. Have a plan.

11. Have a back-up plan, because the first one won’t work.

12. Use cover or concealment as much as possible.

13. Flank your adversary when possible. Protect yours.

14. Don’t drop your guard.

15. Watch their hands. Hands hit cameras. (In God we trust. Everyone else, keep your hands where I can see them).

16. Be polite. Be professional. But, have a plan to take a picture of everyone you meet.

Be careful out there.
