I have been to a few rallies/vigils/marches lately and all incidences of violence that I have witnessed either in person or through media has been instigated by the police. As far as I know,every documented case where a formerly peaceful crowd turns into chaos has been started with police shooting pepperspray, teargas, or whatever into the crowd.
I find it really hard to not come to the conclusion that the police is desperately trying to set a narrative to justify a history of violence by escalating more violence, but please, someone, restore my faith.
Others have already shown examples, however here is an news article covering some incidents: https://www.newsweek.com/fbi-asks-evidence-individuals-incit...
I have so far not seen any evidence of the opposite taking place, I would certainly appreciate some counter examples.
