I have better odds of getting shot by a government agent than being spied on, and I generally manage to get through my day without worrying that I'll die at the hands of the US government. I think that's probably the biggest reason that so few people outside of HN/Reddit/etc. care about Snowden leaks. I can find plenty of people that are upset about police brutality, and there's lots of discussion about implementing body cameras, discrimination in law enforcement, etc. because I can find new, documented evidence of someone getting shot by a cop every other week. It's still not at the level where I worry that I'm going to get shot by a cop. Snowden showed potential for abuse, not actual abuse. That's why "I have nothing to hide" persists.
