A few other thoughts that have popped into my head while trying to catch up with you all:
-having a keg at a party was a semi-big deal in college and would never happen in a scenario where you'd plan for a few people to come over and pre-party. Granted I didn't come from the same financial background as the keg hosts, but we were all about re-couping the costs of the purchase a few dollars per cup at a time. I'd estimate 30-40 unique people over there at a minimum at different points.
-land line phones? I'm just going to have to disagree that they would even be present in any student apartment anywhere in Bloomington. I'm sure they may be present a few spots for unknown reasons, but heavy heavy minority, pretty much extinct.
-IMO probation and fake ID's (especially female fakes) are not really taken very seriously. Again, exceptions to every generalization, but most students wouldn't think twice about continued underage drinking or entering a bar with a fake ID despite being on probation from a prior citation.
-What jumped out to me in the article last summer when the crazy guy was arrested in the Kilroys parking lot ranting about LS:
"One thing to make clear," Qualters said, "he did not have any additional information other than what had been released to the media previously, so he is not considered a suspect and was essentially eliminated as having any involvement in that case.". I'm sure it is common LE practice to hold certain facts back from the media in order to verify someone's true involvement. The talk about the Behrman/Clouse confession earlier reminded me of this aspect after the significant amount of resources that were wasted to drain Salt Creek in that case. LE has more here that we don't know, the relevance of what they have is of course a big unknown.
