The point pro-2nd amendment people are trying to make is, there is no way to solve the problem. Like drug abuse, child abuse, spousal abuse, poverty. There is only trade offs. Everytime there is a tragedy some always ask government to do something. That something is always take away the constitutional rights, and liberty of law abiding Americans.
All of the "solutions" for Sandy Hook are not solution at all. THAT IS THE POINT we are making.
We are not willing to trade liberty for safety or security.
