Does getting a lawyer instead of a public defender significantly help out the outcome of the case and how do you get a pro bono service?

Contrary to popular myth of the accused, PD's are lawyer and many are way better than private counsel . the problem is is that they are overworked. My advice is to be as nice and respectful to your PD but persistent in your need to discuss your case with them. If they still cannot talk to you, look for a private attorney.
