Let me start off by affirming your assumption that the Thomas Jefferson School of Law isn't a complete waste of money because it "seems to attract a large number of applicants and has recently built a new facility in downtown San Diego." Just three years ago a well-known rankings system took the size of schools' libraries into account; accordingly, there is always the chance that a new set of rankings will take the newness of a school's facilities into consideration, in which case Thomas Jefferson would be ahead of schools like Yale and Harvard in this category.
Another wonderful thing about the school is the fact that it is named after Thomas Jefferson. I don't even know what a "Yale" or a "Harvard" is supposed to be, but I sure know who Thomas Jefferson was. This alone adds to the school's prestige.
Finally, people are going to tell you that your postgraduate employment prospects will be dismal if you attend the Thomas Jefferson School of Law. However, as the ABA data for the graduating class of 2011 show us, this just isn't true. Thomas Jefferson may initially appear to have slightly worse employment rates than another prestigious school that begins with "Thomas" (Thomas M. Cooley Law School), but the chances of getting a job at a decent firm are twice as high at Thomas Jefferson. Just look at the following graph if you don't believe me:

In conclusion, I think that the Thomas Jefferson School of Law is a great way to gamble with $275,000. If you compare your chances of getting decent employment (0.8%) to winning any major lottery (0.0000006%), you're leagues ahead of the rest of the idiots out there who are throwing their money away.
