These are police officers.  They have a range of these unconventional weapons to use and no one to watch out for,  as thry choose where and how they decide to slowly murder or sexually assault or rob or torture my family and friends and I. 

They decided the best way for them to do this is by using remote and even satellite weapons. 

This is an illustration of one of these weapons, and why it's not unusual to be assaulted through the walls and windows of your home.
