First amendment, word for word. A business is not a public place. Private property is not a public place. Trespassing is not peaceful assembly as you cannot break the law and still be law abiding (peaceful assembly).
It's simple: If you are disrupting business, private citizens, it is not peaceful assembly.
If it is not peaceful assembly, it is violence. Violence with political change as the goal is, by definition, terrorism.
How does this apply in any way to the post? What does the first amendment have to do with UK law, and how is parliament private property?
ignoring pmya's good point about this being a /s/unitedkingom post, where does the first amendment say anything about a public place? im not reading anything about it needing to be in a public place. that does not apply. if anything you are providing a strong counter point to your own point. im surprised to hear you consider anything thats not a peaceful assembly is violence. i think that opens more doors than you might have thought when typing it.
No, that's a riot.
A protest is to show a large number of people who disagree with some policy and that they feel strongly enough about it to show up all at once in one location.
What you've describe is not "peaceful assembly" and should not be allowed to happen, should not be treated as legitimate in any way.
