what kind of lawyer would i get for a stabbing while my son was in prision\

Assuming you are looking in to recovering for your son's injuries suffered while incarcerated, you would want an experienced personal injury attorney.  Suing correctional facilities for their negligent acts requires an attorney experienced in that area.  My partner, Jon Abernathy, has represented numerous clients who were injured while incarerated in Indiana.  He can be contacted at 1-800-625-4710 for a free case evaluation.
