The claim that guns can safeguard freedom is common in US political discourse. In light of a broadly republican understanding of freedom, I evaluate this claim and its implications. The idea is usually that firearms would enable citizens to engage in revolutionary violence against a tyrannical government. I argue that some of the most common objections to this argument fail, but that the argument is fairly weak in light of other objections. I then defend a different argument for the claim (...) that guns can safeguard freedom. I claim that firearm ownership among members of oppressed groups can hinder the use of systematic violence aimed at preventing them from exercising their basic liberties. I show how a commitment to armed self-defense is compatible with non-violent civil resistance as a tool of political change, and show how the former facilitated the latter during the Civil Rights Movement. Finally, I consider the policy implications of my argument. I don’t think it vindicates lax gun control policies. However, it may vindicate some individuals acquiring guns and learning how to use them, and some organizations aiding them in doing so. (shrink)
