Most US residents worry about leaving their home unprotected while they work or travel. And if
they live in “bad” neighborhoods where crime is frequent, they may even have trouble sleeping.
Unfortunately, living in fear isn’t that unusual today. Elderly people living alone and latch-key
kids at home alone after school are vulnerable and less able to protect themselves. Fear may
even drive people to keep guns in their homes, introducing the risk of being injured or killed by
your own weapon!
