Many Americans believe in following the law no matter what. Snowden broke the law. Gun owners are trying to prevent the law from changing.
But if the government breaks the law, it's OK? When others do it, they're traitors?
Americans are starting to get rather pissed off at the increasingly obvious double-standard that exists when government employees are suspected of crimes, particularly violent crimes by those charged with keeping the peace, and corruption and fraud by those granted positions of trust and authority.
And this is all mostly due to ubiquitous smartphone cameras. In this light, universal surveillance is barely acceptable, just so long as we get to watch them as thoroughly and easily as they watch us. So far, this condition has not been met.
Edit: Not sure why I've been downvoted. I said "apparently many" because I've made the horrible mistake of reading comment sections on articles about the occupation event, and there were a number of very vocal supporters in those comments. To me that constitutes "many" supporters of this position. Obviously I have no idea what percentage of total gun rights advocates are in agreement with the occupation as I highly doubt those numbers exist. In addition, I wasn't even trying to make a statement for or against the 2nd Amendment/gun rights, merely pointing something out.
