Theoretically, yes, Practically, no. If you're paranoid, then announcing that you're going to download Liberte from Sourceforge isn't a good idea. LE could get the server logs. How many people do you think will download Liberte in the next 12 hours? Probably not that many. It puts you on a short list of suspects. Practically, LE doesn't have the time, resources or interest to go after random people who may or may not be low level drug buyers.
