I'm going to make myself unpopular here and say that the answer might very well be yes. I don't think that your physics background matters very much. What schools want are people who will come in and boost their statistics. The 4.0 in basket weaving will probably trump the 2.0 in physics. It is also a terrible idea to go to school based on the assumption that you will transfer somewhere better. Everybody's trying to do that, but not everyone can do it.
That having been said, it might still be worth it to study hard for the LSAT and at least see how you do. Lots of people have been able to raise their score significantly through practice. A high LSAT score can compensate for a bad GPA. To a point, anyway.
I disagree... Your degree background in physics does matter. It definitely trumps my 4.0 in basket weaving! The fact that your LSDAS GPA is going to be low can be explained with an addendum to your application. What law schools want are people who will come in and succeed.
That said... work on that LSAT. If you need to invest a couple thousand in a prep program, DO IT! The difference between a 158 and a 168 is a lot of scholarship money and a guaranteed second look at your application.
There are excellent T3 Schools out there and most T2's will allow you to transfer after the first year if you can stay in the top of your class. We had a couple go to Cooley for a year then transfer in after being turned down.
Your undergrad degree in physics makes you a good candidate for patent law... an excellent area with a great need. Most undergrad degrees are not in a science-based field so few qualify to even go into that area.
Just a thought or two for you. Nothing about law school is easy... they make it like that on purpose. Show them you are prepared to dig in and excel in your application and they will see this dedication will carry over to your law career.
