your example is too simplistic, what are the crime statistics in the area? What is the cost of the extra security? Does this mean you would advocate no matter where the pharmacy is located (high crime area or low crime area) they should all have security guards and cameras regardless of the cost and benefit?
If I own a pharmacy and suffer say a .009 percent of losses due to theft I should take on extra expenses of say 15% by hiring security and installing a video monitoring system in order to stop that .009 loss?
If I own a pharmacy and I am thinking of hiring a security guard it goes without sating that the theft losses are more then the salary of said guard. The idea that voter fraud doesn't exist is a left wing fairy tale. It does. If a Congresswoman is doing it you can feel certain that lots of other people do. There has never been any way to stop it or prevent it so leftists like to point our the low number of arrests made. That's like saying a bear doesn't crap in the woods because no one saw them do it.
