There's no justification for sexual assault.
Not that I'm condoning crime but there's non violent crimes he could've done if he was that desperate to stay in prison.
Unlike some crimes, sexual predators (also domestic violence perpetrators) often don't change their ways, despite rehabilitation attempts.
Also there's many homeless people - including many who have commited no crime. Some are actually victims of crimes, eg. DV is the biggest cause of women's homelessness.
Despite their awful circumstances, most homeless people don't sexually assault people.
(The fact there's homelessness is a disgrace and obviously the UK needs more social housing asap).
I wonder too, am I the only person who thinks the primary purpose of prison should be not what's often debated (punishment and deterrence) but actually protection of the public?
If someone's a danger to the public, they shouldn't be out of prison. (Exceptions if mentally ill and lacking mental capacity. In which case, if dangerous, they should be helped but in a secure setting).
