T1/T2 matters very little in this decision, unless you want to work in high-profile public interest, like the ACLU. As noted above, any state school where you can get instate tuition is good, any school where you want to practice that you can get mad ducats at is good.
The law school most well known for PI work is CUNY. Although it's not ranked high, if you're looking at T1/T2 schools, you'd likely get a full ride.

On USNews, check out the employment stats re: what percentage enter PI work.
Northeastern grads do a bunch of PI work--so do Temple and Rugters (more Newark than Camden)
