Gun Control and Pro-Vaccination Movements Need "Poster Child" Tactic

The gun control movement in the United States is losing massively to the gun lobby. I am amazed they don't adopt a poster-child tactic. There are so many school shootings and similar gun-driven bloodbaths, I am statistically certain that among the tragically bereaved families, there are bound to be some (instantly, former) rabidly pro-NRA acolytes.

So why not try to identify these people, and carefully select from them a few "poster child" individuals, who would sincerely and heartbreakingly explain how wrong they were to oppose reasonable gun control.

It seems like such an obvious tactic, but I have not seen it applied.

Exactly the same reasoning applies to the pro-vaccination argument.
