1. Does everyone have a right to privacy? Why or why not? Who doesn't deserve a right to privacy, if anyone? Why?
Everyone deserves a right to privacy. Everyone. I think it is one of basic human rights that everyone should have.
2. When is an invasion of privacy justifiable? When is it not?
I think the only time it's justifiable is if another creature's life is in danger. Not necessarily immediately threatened, but if there is evidence - more than just suspicion.
If you think you saw something once or you just don't like the look of your neighbor (race, ethnicity, religion, etc.), then that's not a reason to call the cops.
Gah, I'm being so unclear. This is a tough set to start with!
3. Do employers have the right to monitor employee Internet usage (recording keystrokes, surveying email, etc.)? Why or why not?
Record keystrokes, I don't think so. Monitor email, as in how much traffic the person does, yes. I don't think they should read the employee's email, unless they have a high suspicion of the employee doing something illegal.
I know that some companies do survey email, and I can understand why. But that doesn't mean I have to like it or agree with it fundamentally.
There are always exceptions to rules, though. Employees who download pr0n or have a side business while at work are some of them.
4. Are surveillance cameras in banks, ATMs, parking lots, shopping centers, stadiums, etc. an unreasonable violation of personal privacy? Why or why not? When (and where) does the placement of a surveillance camera intrude on privacy?
No, those are public places. In bathrooms, yes, that's unreasonable. Especially if they're in stalls.
5. Does the government have a right to monitor everything we do in the name of national security? Why or why not? Under what circumstances might you support something like TIA?
No, the government does not have that right. See #1.
I can't think of any circumstance which would make me support TIA.
