DOVER , Del. — Large crowds on opposite sides of the gun control debate on Wednesday flooded the east side of Legislative Hall as lawmakers introduced a trio of new proposed firearm laws. The new bills include a revived attempt to ban the sale of many types of semi-automatic firearms — dubbed "assault weapons" by sponsors of the legislation. Lawmakers are also seeking to ban possession of firearm magazines that can hold 15 or more rounds of ammunition and require people to obtain permits from the state to be able to purchase firearms. Second amendment supporters flocked to the Green across the street from Legislative Hall before marching to the east side of the building, the location where Moms Demand Action, a gun control group, was holding a rally of its own to support the new gun bills. During the rally, the second amendment group frequently booed and shouted over speakers from Moms Demand Action and lawmakers who spoke in support of the legislation. However, the confrontation never turned violent during the roughly 45 minutes that the gun control rally took place.
