I have seen it happen first hand. Student's from every law school have been in court opposing each other and when there is an actual case pending the name of your law school means jack. The judge does not say well I believe this girl is lying about being raped because defense counsel went to Harvard. If you get a case to trial the last thing on anyone's mind is what law school the other attorney went to.
In San Francisco Courts they see each other. There are people from every single ABA school here and CBA schools as well. They all litigate against each other, since they are lawyers after all. I have seen about 100 trials in the last year and attorney's school never comes up, but out of curiosity I look the lawyers up on the California Bar website to see what school they went to. So far I have seen people from schools as unknown as University of West Los Angeles School of law up to schools like Harvard. San Francisco is a destination for a lot of people from a lot of different backgrounds and if they are lawyers they can and do end up in court against eachother.
Let me ask you this White Rabbit, I assume you enjoy the legal profession. What would you have done if you got a 155 on the LSAT. Lets you tried your ass off and 155 was the best you could do, would you have still gone to law school?
A tier 3/4 degree can provide that, it won't work out everytime and it might turn out miserably, the lower down the totem pole you go the more of a risk you are taking. This is not news or should be news to any tier 3/4 student, or tier 4 dental school, med school, nursing school, etc.
