I was charged with felony assault in the 2nd degree. I accidentally injured the other person while trying to defend myself. the other person had a knife and I threw an object in their general direction to get them to move so that I could escape and it might have hit them. The other person is saying that there was no knife, but they are lying about that. we were the only 2 people there,so who does one believeIs it possible during the trial to bring up evidence that she is a liar about so many other things to show her character How do I know who is the right counsel to choose fo this?
