This is a fucking travesty, no justice at all.
Something very similar happened to someone I knew. Got off with manslaughter after essentially putting her life, mental health history on trial instead of him - the pillar of the community who first strangled his wife over a petty argument, then fetched a hammer from the shed to smash her head in. Manslaughter, and back on the street in under four years.
For Clare's family - know you have support, from decent people everywhere. This is not justice.
