Amen to that one. There's a big difference in protecting assets vs this (virtual) panopticon.
My day job mostly involves installing and maintaining security and surveillance equipment. Usually for government agencies. But what my job entails isn't much different than protecting your home or business with ADT, etc. Just on a large scale and a bigger budget...(and outdated regulations).
Ie. It's a government facility. There is CCTV in use. There are security systems in use. Entering the installations is giving consent to being monitored, searched, etc. Using their phone system is giving consent to having your calls recorded.
The same as if your employer has CCTV and the ability to search your possessions on their premises. For the government installations, this is all pretty much a given (and aptly advertised). This, to me seems fine. Much the same way I'm fine with stores having CCTV in and around their buildings.
The problem areas are with agencies like the NSA that have basically been granted to ability to look at and listen to whatever they want, whenever they want.
