Yes, and watch Boston Legal for more ways lawyers can get over on the system...
Movies are not real life!
You may not be doing yourself any favors by trying to discredit a 12 year old child; you may make her look like more of a victim than she already may be.
Op, you need to step back and consider that this girl *may* be telling the truth.
I'd step very carefully were I you; you have children you need to protect. Your husband *could* be lying, or he *might* be telling the truth. If they did find his pubic hair in the bed, I'd take that into serious consideration.
I wish you well.
