Did Daniel Mauser actually throw a chair at Eric? It’s seems more likely he jerked his arm after he was shot in the hand

Near the end of the shooting spree in the library, Eric Harris approached Daniel, who, like the others, was hunkered down under a table. According to various reports from witnesses, Harris taunted Daniel by calling him a geek, and reportedly referred to him as “four eyes” because he wore glasses.At 11:34:55 Eric Harris fired a bullet from the Hi Point Carbine. It pierced Daniel’s hand but probably was not life threatening. Daniel pushed a chair at Harris. Daniel paid for that act of defiance and self-defense, as Harris called out, “Get up!” and at 11:34:57 fired another bullet, this time into Daniel’s face. The bullet entered near his nose and traveled into his brain, likely killing him quickly. God rest his soul.

I don’t think we can really say for certain if Daniel pushed the chair in just a reactive manner in the very moment his hand got shot. It’s difficult to say for sure whether what he’d done in thrusting the chair forward was some sort of intentional, confrontational fight back, as futile as that would’ve been. We’ll just never known for certain, I’m afraid.
