I am against the use of cameras. I visited the school recently to pick up my son and it was like visiting a prison. A police car often sits outside the school and upon entry a security guard directs visitors to the main office where the visitor’s drivers license is scanned and information including date of birth is collected (is this information checked against other records and kept in a database for future reference? It’s unclear).

The visitor is then photographed and issued a photo pass. I found the experience oppressive Adding cameras will only add to the prison‐like atmosphere. The response, of course, will be that these measures are necessary for “safety.” As with security measures at the airports I doubt that these measures increase actual safety, instead they are security theater, a play that we put on that looks like security but really is not.

Quite honestly this is my biggest complaint concerning the increasingly intrusive security measures we’re being asked to accept. They’re put in place more for the appearance of security rather than the actual level of security they can provide. To top it all off, levels of violent crime have been falling dramatically over the past 20–30 years, yet we’re all under the impression that violence is at an all time high.
