What the hell has that got to do with what I said?!
I'm not saying everyone with a mental illness commits a crime.
Good Lordy lord.
You said "a large majority of murderers suffer from mental illness" and that isn't actually correct.
"Homicide
Every homicide is a tragedy, for the person who has been killed and their family and friends.
The total number of victims of homicides in England and Wales has declined in the last ten
years. In 2003/04 the number was 775 (Home Office, 2010-11), while in 2012/13 the
number of homicides was 551 (ONS 2014). The number includes victims of all homicides –
committed by people with and without mental health problems.
The number of homicides by people with mental health problems (called patient homicides)
is measured in an annual report produced by a research programme based at the University
of Manchester. This report seeks to help prevent homicide by people in contact with mental
health services.
The most recent report (NCISH, 2013) covers the ten year period from 2001-2011 and finds:
In the ten years from 2001 to 2011, 602 people convicted of homicide in England were
identified as patients, an average of 56 per year.
In the ten years from 2001 to 2011, 29 people convicted of homicide in Wales were
identified as patients, an average of 3 per year. It is important to note that although these perpetrators have mental health problems, we do
not know whether the mental health problem led directly to homicide. As discussed above
there a many other factors which can contribute to violent behaviour.
There are also some limitations to this report which it is important to be aware of:
In order to be included in these figures the perpetrator (the person who carried out the
homicide) needs to have been in contact with secondary mental health services in the 12
months before the offence.
A separate figure is provided for people who had symptoms of mental illness at the time
of the offence, but were not in contact with mental health services. It cannot be said
whether these symptoms led to the homicide.
The figures do not include homicide where the perpetrator later took his or her own life
as well and was therefore not charged and/or convicted. However not all suicides are
mental health related.
The figures count the number of perpetrators who were convicted of homicide. In some
cases a perpetrator may have killed more than one person meaning the number of
victims is likely to be higher. "
