They're even very clear as to who says what. Note, I never claimed to be providing a fact check entry. Rather, the post I was responding to requested, "Is there a news story, social media discussion, some other documentation of the incident?" The answer is, "yes, lots." Depending on where you source your news, you either heard about it a ton or heard about it none, but rarely in between.
Again, only protester accounts, claiming that police threw a weapon with which they weren't even equipped.
The punctured-tanks-as-weapons theory sounds credible, and I doubt any of those protesters could properly identify a concussion grenade if they saw one (nor could most people in the general population).
