I'm hardly an advocate of the typical right-wing position that guns keep the government in check.

But I do foresee a situation where there's a clash between the well-fed police (who want to keep it that way) and the starving poor in the US. The inner city riots will not be an issue, most metro PDs have experienced and well equipped riot control departments.

It's the armed, rural uprisings that pose a threat. Think Cliven Bundy-types leading a group of protestors in sieges of government or office buildings.
