With all the home invasion robberies going on these days you never know, when the next faint knock on the door may escalate into the door being kicked in and an entire family being held at gunpoint.
It is better to be safe, than sorry or perhaps even dead as I would not be surprised if there is a street gang out there that dresses up like Girl Scouts in order to gain homeowners confidence.
We do not have enough information to know what happened.
I suspect a hoplophobic father and a prudent homeowner who answered the door with a gun in hand and never pointed it at the girl.
How many cases have we seen where people were accused of pointing guns at people (just to make the accusation more dramatic) when they never did so?
That is a rhetorical question. I have read and been told of dozens of cases where that occured.
