Not necessarily. A PD might well be much better than an affordable private counsel. It's definitely better to go private if you're rich, it depends on specifics if you aren't.
You know when I faced this I called around and talked to three attorneys. Your comment may be more accurate then I realized at first.
One attorney I talked to was relatively inexpensive but I can tell I had a grudge against the cops and the justice system in general. They were not going to be a good pick
The second attorney I talked to said for $10,000 they can make this all go away. And they wouldn't file a tort. That seems more like a formalized punishment that I choose than justice.
And the last one was 2500 bucks she said I needed a trial told me why and that's the one I picked and it was a good experience overall. We filed the tort I got my money back and it was a couple of years and I came out clean.
So yeah, it does depend on specifics. And you're right to say that people shouldn't rule the public defender out. Good comment.
