GOP calls for broader gun rights, unlimited clips.Is this stupidity or what?

Republicans have strengthened the pro-gun-rights portion of their party platform, including a new call for unlimited bullet capacities in guns, in a defiant response to criticism that followed recent mass shootings at a Colorado cinema and an Arizona congresswoman's gathering.
What i am now confused about now is why will they strengthen the gun right it is that same right that made it easy for  those guys to carry out their crime...oh sorry,i forgot it's none of my concern
