I think the point here is that if you walk into work with your mini minalta 007 type camera its pretty obvious your upto no good. With the proliferation of camera phones, from a security pount of view. Spotting the person involved in a spot of industrial espeonage becomes that bit more difficult. Basicaly i think that if you wouldn't be allowed to take a normal camera into an area at work then you won't be alowed to take your camera phone there either.

Recently a man was prossecuted for taking a picture with a phone in a court here in the UK.
