PS, I started the process of seeking a concealed carry permit immediately after the Sunday morning I was the near victim of an attempted strong arm robbery at the age of 17. Had it by the age of 19, and have not been without the option of carrying concealed since, other than in those areas where it was illegal for any but law enforcement to carry.
