People like Snowden are heroes
Snowden himself disagrees with your assessment.
Charles Barkley doesn't think he's a role model either, but guess what... he is. When people do extraordinary things, there is a significant chance that millions of people will hold such actions in high regard and elevate said person to 'role model' or 'hero' status. Snowden is a hero for the simple fact that he ousted illegal activity by a government organization. If the actions weren't illegal, but were just 'super secret', Snowden would be a traitor and should hang. But no, all he did was risk his own life to expose quite possibly the worst betrayal of trust the U.S. government has ever bestowed upon its citizens.
Q: How will you deal with [scientific challenge]? Obama: Create/expand a government program or incentive (with no explanation of what existing programs will have to be cut to compensate)
Nothing will be cut. There is no explanation on where the new money will come from to fund said new program.
