Those opposed to this argue that "those deranged people" could find a weapon regardless of the legality of it... Further, they argue that the solution is to medicate those who are "deranged". Doesn't this argument cancel itself out? Those same "deranged people" can just as easily (more easily?) just not take their meds... Do both. Get mentally ill help that need help, and also make it as difficult as possible for them to get their hands on weapons of mass murder.
