"It happened at the Subway restaurant, 3200 N. Rock, around 11 a.m. Monday. Police said two teenagers, 15 and 16-year-old boys, walked into the building with their hands in their pockets, ordering everyone on the floor."
Apparently, no charges have been filed yet. They should.
That situation could have escalated in the blink of an eye, destroying the life of one or more of those kids, their parents and any citizen of the mind to confront them, armed or not.
