Along with property destruction, there are also tactics such as occupations, sit ins, etc, where a crowd of people rush through a door and suddenly are taking over someone else's space for political purpose: no business as usual concept.

Let me forward the example of an unfair/illegal eviction of a woman and her children from a apartment for illegal reasons. As a response, a political/social justice group might occupy the landlord office in response to eviction.

Now, one side could call it an just occupation. The other side could consider it an act of violence.

another example is one that Michelle pointed out with OCAP:

her quote: "For instance, that eviction of the Harris Tory politician's constituency office (forget his name) is an action I support, even though I realize it probably scared his office staff.  Well, that's what an eviction is like.  Scary.  I totally support OCAP's action in that matter."
