In reference to how police/SWAT teams will "stack up" when entering a building, it is a challenge to government officials and law enforcement agents to personally and physically enforce gun control legislation. Most commonly used in libertarian/anarchist Twitter circles when responding to pro-gun control politicians, similarly to "Molon Labe"/"Come and Get It"/"Come and Get Them".
