My wife and I had an argument one night when she bumped into me angrily. I pushed her back to stop the physical contact and walked away. Next morning, we argued again but with no physical contact. After I went to work, she called police and showed them a barely visible abrasion on her arm claiming that it was caused by that brief contact the night before, and I was the one to blame. I was arrested and charged with domestic violence battery misdemeanor. There was also a restraining order issued against me. There was no other eye witness at the time when it happened. Will I, or a competent criminal defense attorney, be able to tell the jury the truth and use self-defense to win the case? What are other defenses I can use?
