... attacks on people with disabilities are often overlooked because many people are not aware of the extreme vulnerability to maltreatment that accompanies such disorders as cerebral palsy, autism, multiple sclerosis, learning disabilities and mental illness — even though, according to anonymous victim accounts from the Bureau of Justice Statistics, the 54 million Americans with disabilities experience serious violence at a rate nearly twice that of the general population. Their risk of being a victim of sexual assault is at least four times higher than that of people without disabilities. In 2008 alone, Americans with disabilities were victims of about 47,000 rapes, 79,000 robberies, 114,000 aggravated assaults and 476,000 simple assaults. Adding to the trauma of victimization, people with disabilities are much less likely than able-bodied victims to seek medical treatment for their injuries, often choosing, instead, to suffer in silence.
