Opening the door is both a literal act and a figurative one. They both imply receptivity. There is little doubt the boys knocked on many doors that were not opened that day, hopefully mostly due to practical reasons (no adult was home; those who were home were occupied with tasks) or benevolence rather than any racial factor. Many who peered out to see who was on their doorstep very reasonably would not have answered because four boys, two of whom were in football jerseys, unexpectedly showing up would in all probability be wanting to sell something, and those who already had certainty that they were not interested would have felt it more kind to not open the door, and therefore open up their hope of a sell. They wouldn't have squandered anyone's time. My family used to live in a well-known wealthy area, and we constantly had people knocking on the door wanting something - to make a sell, to proselytize, or some other desire. Decades before we ever lived there a celebrity had so there were fans who'd knock hoping for a glimpse inside. We usually simply did not open the door to strangers, unless they were children at the age to be playmates for my siblings or me, but the few times we did we'd always see how that action lit this light of excitement in their eyes, regardless as to their biographical specifics (age, race, etc) or what their purpose was for being there. So if we weren't interested in giving them our money or our time, we didn't ignite that possibility knowing that we'd then be quickly extinguishing it. And if we had any fears of the person(s) approaching the house for whatever reason the very last thing we'd do is rush out to confront them.
From the article it's not clear if the kids even had the chance to knock on the woman's door since it states they were just approaching her house. It's obvious that she did open the door since she confronted them with a weapon. That defies reason; it's counterproductive in every way. Had they in any manner behaved inappropriately, such as refusing to leave after a sensible length of time made it clear the door would not be answered, or attempting to enter the home uninvited, she would have stated that as her defense. But she did not. She is the one who was the aggressor and needlessly inflicted trauma upon these kids.
It mentions in the article that her mugshot wasn't immediately taken due to a "medical emergency" which is likely bogus, that she was receiving preferential treatment due to her husband's position, or it could actually be legitimate. Her actions do not fall within the parameters of normal whatsoever, so it's possible something has caused an impairment to her judgement. In a photo of her and her husband, she's wearing noise-canceling headphones at some gathering, which is odd. Whatever the case, he's now resigned from the position, and they are moving. Their neighbors are glad they are leaving.
