I tried looking this up but I haven't really found anything. Maybe I just don't know where to look. There is a sign at work (private company) that all bags and articles are "subject to search". I've seen the same thing in government facilities I visit. Can they really search me without a warrant if it's private or government property? Do they get an exemption or something? Can I be pat down on a government facility just because someone thinks I look "funny"? Can my company just search my bookbag on a whim? Do I lose my rights if they have these stupid signs? I when I see this crap. Does it have any weight to it?
