Most is down to sheer laziness and wanting to "work from Home"
Im sure we have all heard about how one day we will all work from home blah blah.
One of the reasons surely people did all work in one place was down to these basic security principles. Dont let information go walkies.
The police are very good at forgetting procedure and leaving paperwork lying around from personal experience.
I had to wait in a Police canteen in a central London Police Station recently, I was au fait with much of the days work. As well as me were plenty of other outside guests in their for one reason or another. No wonder the press know so much.
I have also been left to wander around New scotland yard and other stations on numerous occasions and leaving with more items and documents than I entered with. Basically like the country they only check you on the way in
But generally private comapanies are hot on security and Goverment and council offices are years behind.
Strangely the Police are just to friendly and trusting when you meet them business wise.
