Two groups of men had a discussion inside a mall that allegedly led to a knife being drawn, followed by gunshots that did no injury. No charges have been filed. Police are still investigating.
The alleged shooter was a 19-year-old man who had a license to carry a concealed handgun.

Money quotes from (I guess) random interviewees:
Impossible. Unimaginable.No, I would not expect anybody to have a gun inside of a mall. I don't expect that.
Why? To use them as decoys?Anytime after 6 o'clock, when it gets dark, I wouldn't be shopping, not unless I had my family with me.
Indiana has a licensing system that is not exactly shall-issue, though in practice it usually works that way. Anyone 18 years of age or older can apply for a license. The fee is $10, half of which is refunded if the application is not approved.
The law requires that the applicant
Indiana grants non-resident licenses only to persons who have a business or employment within the state.(1) has a proper reason for carrying a handgun;
(2) is of good character and reputation;
(3) is a proper person to be licensed;
