The World War II hero who proved it’s possible to beat the NRA

Some heroes never stop fighting. 50 years after he helped liberate Dachau, Felix Sparks lost his grandson to gun violence.

His passionate fight for better gun control reminds us that it is still possible for one determined person to triumph over political giants.
