In plain view means just that, in plain view. Even using your analogy of headlights on a police cruiser, you still can't use headlights to peer into someone's house THROUGH THE WALL or ROOF.
Helicopter. It may not necessarily see THROUGH your roof, but it still has a good Point of View. I have no problem with a helicopter though, so long as it still uses observation methods that more or less follow the same pattern of human sensory perception.
The spirit of the law is that people have the right to do just about whatever they want in their house, behind closed doors/walls without being subject to a "casual inspection" by the police.
It's not just your home. The entire idea centers around the 'expectation of privacy'. It appears that the expectation is diminishing NOT because of a sudden desire to share with the world, but because of zealous law enforcement. After all, who doesn't want to succeed at their job AND make it easier at the same time? http://en.wikipedia.org/wiki/DNA_profiling#Surreptitious_DNA_collecting That link is an example of how law enforcement gets creative with the assistance of scientific advance. Fifty years ago, the thought of someone identifying you uniquely by digging your coffee cup out of the trash at a crime scene and swabbing it would have been absurd. Now, it's just common practice.
Basically, if it isn't grossly obvious that you're doing something illegal, the Police should leave you the hell alone and go find someone who IS breaking the law in public. In my experience, that's not a very difficult thing to find...
Bad logic. Some of the most heinous crimes are those which are not readily visible. Pedophiles are basically invisible. Stupid drug dealers get caught, but smart ones and distributors farther up the food chain remain free people. I've seen these often enough to understand why law enforcement digs around. Doesn't mean I'm personally willing to trade privacy for a cleaner world, but the 'reasonable person' is.
...They gave her the info so she could be compensated for the damage done to her property. That's right; they're paying for the damage...
Good deal, I say. Get your laptop blown up with an offer for compensation and you EVEN get to keep your data. Best Buy would take both and treat you like a terrorist for complaining.
After any salary raise, you will have less money at the end of the month than you did before.
