Chris Mintz is the Army veteran who was shot at the Oregon Community College; he attempted to block the door as the shooter opened fire. Mintz was shot seven times and will need extensive therapy to recover.
This is a man who put his life at risk to save others, and doubtless did. Thus, he is an application of the wisdom: “He who saves a life shall be counted as though he saved the whole world.”
I encourage you to go and give what you can.
