It's worth noting that this was after the U.S. killed their top general illegally and they expected a strike on Iran after hitting some Iraqi bases in response to the U.S. assassination.
So they made us, the civilians, their meat shield, just as they used us to clean minefields in the Iraq war. And then they were so incompetent they shot their own meat shield. After that, they launched massive media campaigns to say the plane had not been shot, but had crashed out of a "technical glitch." Even after the evidence became undeniable, and they issued public apologies, they still continued with their media campaigns, saying this was all because of a US cyber attack. And they did not let people organize proper funerals, and they imprisoned, threatened, and fucked the survivors' families, and they used tear gas and just straight opened fire when people protested at their sheer malicious incompetence, and ...

The gov comes down hard on people saying they don't like him, so the answers people give are biased. How biased, I don't know. I can tell you that even people who liked him still got outraged at the plane shooting.
