sometimes I'd imagine a couple weeks of class will get people to chill out and realize how little they know...
It isn't just the young 21-23 year olds who are behaving in this way. There are lot of mature traditional students whom I respect a lot more than some of the non-trads who are using law school as a launch pad for College Part II.
there's also the possibility that the lawyers you knew were just a good group of people (were they all from the same firm? In which case they probably self-selected themselves - decent people tend to enjoy working with other decent people)
I think it matters, and I only say that because where you work your first job after graduation depends a lot on where you went to school, and that job sets the trend for most of your career.
I left my slightly lower ranking school for ND. I have no regrets at all after seeing the stats that firms required/preferred at my old school's OCI. While ND doesnt exactly rank its students, the same firms recruit 10-20% deeper at ND. Additionally, more firms from various locations recruit at ND than at my former school, where ~95% came from the same state and a neighboring state. You may not care as much since youre looking at Detroit and IU may have plenty of Detroit firms recruiting there. Just for one eg I looked for the reqts that a Detroit firm has at ND. Foley & Lardner - 33%/3.4/3.33. If you can, compare that to IU and consider whether the increased % (if there is one) is worth the money.
Jew scammers at Roger Williams law school admit to lying about employment rates and even salary statistics but they won't do anything about it. They also admit the school hates blacks and poor people.
