From watching the video (advice for those on this side of the Atlantic), here are some recommendations:
1. Grab the folks documenting the incident first. Relieve them of their recording equipment.
2. Make sure those near the front of the blocked traffic are documenting what will take place next.
3. Inform drivers in front of line to be prepared to run down any armed protestor upon production of a weapon.
4. Disarm any armed participant. Use of force here is acceptable as a means of self-defense.
5. Using rope or jumper cables, remove each ‘protestor’, tying hands to guard rails outside lanes of traffic (handcuff assistance acceptable). Note: once this happens to the first couple, the rest may scatter. This is an acceptable outcome).
6. Check and document any identification found on the law breakers (including tattoos, piercing’s, etc.
7. Photograph each participant; broadcast gathered information on social media.
8. Informed said law breaker their personal information has just been made public.
9. Contact local law enforcement informing them of the debris left on the side of the road.
10. Rinse, repeat.
