From Ammoland:

In reality, those professionals customarily considered “first responders” are, in fact, second or third responders to dangerous situations. It is critical to the Second Amendment movement that it is understood that the real “first” responders are almost always ordinary American citizens. The citizen who first encounters the person having a heart attack in the mall; the citizen who sees the criminal holding up a cashier across the street; the citizen attacked by a violent thug; the citizen who notices that the neighboring house is on fire: these are the true first responders.
