Re: Why not?
Electronic IS totally different. It's not a physical thing they are looking for that you might have in your briefcase, be it a weapon or drugs or whatever - it's all about data. I'd bet you be none to pleased if some jobsbody got your private diary out of your briefcase, brewed up a pot of coffee, pulled up a chair and started reading through your life for the next 12 hours. That sort of intrusion is the exact sort of thing you would expect would require a warrant.
I admit my total ignorance in the law on this (where such a thing may exist), but I'd hoped we were at least living in a world where most people would consider this sort of action as just fundamentally wrong!
