The legislature in VA is pushing a number of bills that are aimed at "downstate" and conservative, rural, working class people. Guns are just the first issue to be tackled by the Progressives in Virginia.
When someone says "school shooting," a lot of otherwise well-intentioned people (e.g., the soccer moms of NoVa) have been told the answer is "gun control," which somehow translates into taking guns away from law-abiding citizens. Those are the votes the Progs harnessed in the last election, and the people they are pandering to with draconian gun control legislation now. (My own thinking is that there are lot of closet gun owners in NoVa, people who are professionally successful in this government employee, contractor, IT services-heavy environment, and who want to protect their homes and families. Living in NoVa, they are just too embarrassed to admit they have a Glock in the dresser drawer).
