The loss of pay phones over the last 20 years is a loss to society. We used to have widespread access to cheap and anonymous emergency calling.
The local university here has these emergency call-for-help stations all over campus. They have a blue light on top so they are easy to find especially at night. A couple of years ago there was a little feature story in the newspaper about how they had never--not once--been used in a real emergency. But the university did not want to take them down because they provided a feeling of security.
How many real emergencies occurred near one of these boxes?
Creating a feeling of security is as important as creating security—you need both.
