I recently posted a new draft of my forthcoming article, Four Models of Fourth Amendment Protection, on the meaning of the “reasonable expectation of privacy” test. I normally wouldn’t mention a draft revision, but this one is substantially reworked and simplified; if you’re interested in the Fourth Amendment in general and the reasonable expectation of privacy test specifically, you might want to check it out. I might also try to do a few blog posts about the article, and to respond to some of the interesting comments it has triggered, if readers are particularly interested in that.
