What should I get my bachelors degree in to become a criminal defense lawyer?

Law school is just a numbers game. Don't worry about the subject (about half of applicants have a Science based degree and about half have a language based degree) and don't worry about the Community college. You need an undergraduate GPA of at least 3.5 and a high score on the LSAT (at least 70) and then you will apply. Go to the best Law school you can get into. With respect to the branch of Law you go into, you will not need to be concerned about that until you are in your second year of Law school. Criminal defence is poorly paid but prestigious. You will need to join the right firm after Law school (be sure to be in the top 5% of your graduating class) and then take pro-bono cases to build your reputation. You will probably need to take bar exams in a number of states as your clients could be anywhere. Mostly, they will never be able to pay for your services by the nature of who they are so have a successful spouse or come from a rich family. It is a very rewarding calling.

a degree in history or political science is a good foundation for law school.
