Actually yes, that's exactly what it means. Warrants are in place to protect people from illegal search and seizure. If during the course of a legal search items not covered in the original warrant are found the officers are required to attain a secondary warrant for the new items. In regards to your stop sign example, they do that too, and that's exactly the problem. Law enforcement agencies constantly step over the line, which is unacceptable. they often act no better than the criminals they're trying to catch, illegal wire taps, illegal broad scope searches, excessive force... On the west coast of Canada -where I live- the police have been accompanying "electrical inspection teams" whenever a house has a higher than normal power consumption. They are illegally searching for pot grow operations under the guise of a safety inspection, our own courts have deemed this unlawful. Take the examples of the RIAA and law firms in the UK sending out random letter to "possible" copyright infringers demanding payment for downloaded music. This is nothing more than extortion, there is rarely sufficient evidence of the crime. It amounts to the enforcment of criminal law by civilian persons through civil litigation, which... Is against the law. The list goes on. We live in a society where our civil rights are supposed to be protected, this "well I have nothing to hide so search away" attitude just diminishes the freedoms and protection we are guaranteed by our charters. Personally I never agree to willful searches or any other conduct I dont explicitly have to agree to. I'm not hiding anything, but the rules are in place for a reason.

Wow... The random clandestine online search of SUSPECT computers is a travesty against our rights and freedoms. There is no justification, period. Any form of search and siezure requires a warrant -as it should- which can only be attained after some form of investigation. In essence, proof of illegal activity must be aquired BEFORE the authorities can do anything overt. This is how it should be, checks and measures in place to protect our rights. This "I have nothing to hide so come on in and search away" mentality is ridiculous. It doesn't matter whether you have anything to hide or not, you have the RIGHT to not be subjected to unreasonable search and siezure. This is a fundamental aspect of western society, and it requires the perserverance of the people to be maintained. We are seeing this basic principle being abused daily. I don't support online illegal activity, I hate spam just like everyone else. However, I also know that any computer suspected of illegal online activity has an IP address attached to it. With the proper investigations and warrants, perfectly legal search and siezures can be performed in a transparant fashion. If the computer lies outside the physical boundries of the laws, then guess what... you don't have jurisdiction, maybe it's time to talk to the law enforcment agencies in that region that do have jurisdiction. If we allow these agencies -government- to run "roughshod" over the rules in place to protect us, we are contributing to the breakdown of our social structure. keep it in mind, the government works for us, not the other way around. -at least in the free world-
