The filibuster lets a legislative minority permanently block majority-supported gun reform

Evidence

With the congressional ban on even interpreting gun-related data, the gun lobby has a complete stranglehold on Congress on any issue concerning guns. Lawmakers of all stripes shun gun-law proposals. Progun advocates oppose them. Those favoring gun regulations know that, even if the majority of legislators support tightening gun laws, they cannot muster the votes needed to override a filibuster. So they have become resigned to the reality that they cannot enact gun reforms at the federal level. — Albert Bandura, Moral Disengagement, 1325
