Assignment:
The line drawn to mark where and/or when you have a "reasonable expectation of privacy" can get quite fuzzy, particularly in this age of evolving technology.
Scenario: Your government employer seeks to search, without a search warrant, the records and transcripts of the text messages you had sent on an employer owned device (cell phone, etc.) or the information and e-mails stored on a computer in your government office. What are your arguments for claiming that you had a reasonable expectation of privacy, and that the searches violated the 4th Amendment?
Let's change the scenario a bit - What about private text messages or e-mails sent to your spouse from the same government owned devices, but while you were at home and off duty?
In either of the above cases, does your spouse (or other recipient) have a reasonable expectation of privacy in the transmissions?
Finally, what about private data, images or information stored on a personally owned thumb drive that you attached to a government owned device?
