Banning concealed firearms only makes it better for the criminals and terrorists. Thomas Jefferson knew this over 200 years ago when he said "Laws that forbid the carrying of arms... disarm only those who are neither inclined nor determined to commit crimes. Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than prevent homicides, for an unarmed man may be attacked with greater confidence than an armed one." Why do some people need to keep relearning the same lessons?
