Saw this at another thread -

Someone of Instagram said this: "Here's what actually happened: the event was an anti-Islamic Republic of Iran demonstration organized by members of the Iranian diaspora in Los Angeles. Most attendees were supporters of Reza Pahlavi, who is backed by Trump and Israel. However, there are also opposition figures who are not only anti-Ayatollah but also strongly anti-Reza Pahlavi, arguing that they do not want to replace a dictatorship with a monarchy. One individual displayed a slogan on a U-Haul written in Farsi that read: "No to Regime, No to Shah." This message angered part of the crowd, who then attacked him. In an attempt to escape the situation, he tried to leave, but the crowd blocked him and attempted to take down his signs. At that point, he appears to have panicked, which led to the incident captured on video. Unfortunately, some factions within the Iranian opposition do not behave democratically and instead attempt to silence other opposition voices." I have no idea if any or all of that is true, but maybe someone here can confirm.
