US Weekly reports that
NCIS star (her character's name is Abby Scuito) was attacked by a homeless man on Thursday [November 12 ] near her home in Hollywood. Perrette composed a letter describing the ordeal and snapped a pic of it, which she then posted on

While William was arrested and charged with "felony assault," Perrette declares that further changes need to be made. "We need full mental health care," she begins. "We need housing and help for the homeless. We need to support our cops. We need to not walk alone."
