So here's a related situation of a Police Officer actually assaulting a chap on a tube in the UK for not wearing a mask. The guy rejects strongly, and whilst I don't advocate the aggression, nevetheless, the police officer is assualting him by man-handling him and he has every right under the law to defend himself.

If people understand the common law, this can much more readily be dealt with using the following statements...

I. I am exempt from wearing a mask for health reasons.
2. It's against the equality act to try to force me to do so.
3. I have no contract with you.
4. I do not consent to the coronavirus act.
5. I stand under the jurisdiction of the common law.
6. If you arrest me under the act, that is false arrest and kidnapping.
7. If you put your hands on me, that is assault.
8. What is your name and number?
9. I hereby serve you a personal notice of liability to the tune of £10k for assaulting me.
10. I hereby serve you a personal notice of liability of £20k if you conduct a false arrest on me.

This is what we must learn and be prepared to act upon. Notice in the video how the fellow passengers come to his support. In Italy right now, 50,000 shop keepers are defying the lockdown and opening their businesses. Where the police go into the shops and try to close them, they're finding themselves surrounded by customers who are strongly protesting.

So again, I ask the questions: what is the cost of your freedom? What is the price of your soul?
Only your soul can answer that in any given situation. But we need to be clear that we're not simply compromising through fear of the potential outcome.
