Colorado Governor Signs Sweeping Gun Control Legislation in Response to Massacre.

Colorado's governor signed four gun control bills aimed at preventing mass shootings, reducing suicides, and opening avenues for gun violence victims to sue the firearm industry. The bills include raising the buying age for any gun from 18 to 21, establishing a three-day waiting period between the purchase and receipt of a gun, strengthening the state's red flag law, and rolling back some legal protections for the firearm industry. Gun rights groups have already sued to reverse two of the measures, and Republicans have decried the bills as onerous encroachments on Second Amendment rights.
