A friend of mine lost custody of all 3 of her children on Friday, due to drug charges. Her last go around with the police she got a total of 6 charges 3 related to PCP. She was already on probation for previous drug charges. The judge order a hair follicle test, and the children where to immediately be handed over to their father. Her lawyer told me that the fathers lawyer was going to force me to testify against her in regards to her drug use, me and my sister to be exact. She is really a friend of my sisters who I see on occasion at family dinners. Can I be forced to testify against her?
