Knock knock burglars – how to prevent home invasion using security screen doors

Knock knock burglars – how to prevent home invasion using security screen doors.  I would like to share an incident that happened to my family about two weeks ago:
My daughter and I were working on the computer in the front living room late at night around 11:30 pm.  Some gang banger knocked on the front door and we did not open the door.  It’s like they want to say knock knock burblar and expecting me to say who’s there.  We have one of those small hinged peep doors. Not knowing who it was, I proceeded to open the small opening to look outside. Additional knock knock burglar cases posted.  Check it out.
