An uninsured motorist ran a yellow as I was making a left turn (in CA), we collided. Wouldn't it be her fault?

This happened in Los Angeles County. All other cars stopped, except for her. The light had turned red by the point of impact. Wouldn't it be her fault? We exchanged info, I took pictures of both cars, then she left. She came back with her husband, and he started taking pictures of my car. He then started yelling at me, saying it was my fault! He wasn't even present at the time of the accident! The nerve! He threatened that he was going to sue me!! WTF? His wife had NO insurance!! If they find me at fault, can they still sue, even though she's not insured? Any advice is greatly appreciated!!
