About enforcing the gun control laws (if they get passed)- nobody said it would be easy. Enforcement is rarely 100% but it is still better than 0% enforcement (meaning no gun control laws). It will take time, training and efforts to implement it, and even a small success is progress when you compare it with what's going on right now. It is hard to predict whether an adult carrying a gun at Sandy Hook could have prevented the loss of so many lives. We are talking of possibly a single shot gun vs an assault rifle that was military grade. I don't think that would work. IMO the more important thing is to not encourage people to buy even more guns because of gun violence. The real need is to get away from violence, and not let it increase exponentially (IMHO it already has).
