Denver made a similar report, but have not made their arrest records public, for some reason...
Why do you think people are protesting or rioting? There are a ton of people who feel like their desire to change "the system" is falling on deaf ears.
Elections and lawsuits are really the only meaningful power the average person has over those in power. Other than that, it's up to people in power to check others in power via "checks and balances".
I might be naive, but I think most populations around the world would have revolted much earlier if they were armed the way americans are.
The 2A's only role in US society is to allow some people to buy some small arms some of the time and otherwise doesn't have any place in America until the country falls (at which point all of the laws/amendments are not relevant). It's not like you can use your weapon on a government official and claim under the 2A you were protecting yourself against the government. You still get prosecuted for murder; only jury nullification would save you at that point.

You forget that our military is the largest in the world with lots of recent experience in {counterinsurgency, counterterrorism, and psychological operations}. They also have some of the best tools for identifying where most people are and are capable of shutting off most mass communications within the US if they needed to.
In the end, the political polarization is such that those who own lots of guns tend to be the same demographics who revere police/military/order and are currently in the camp that overlooks / detests the protesters, saying their complaints are overblown. I'm pretty sure that's largely due to a sustained PR effort by the post-WW2 Defense Department including sponsorships of sporting events that are more likely to attract those same demographics.
