After the horror that is Craig Sweeney - released early from a 3 year term for sexually assaulting a 6 year old - abducted and severely assaulted a 3 year old girl - there has been significant public outrage in the United Kingdom.
The mother of the 3yo, Home Secretary John Reid and junior constitutional affairs minister Vera Baird have all come out in the media stating their dissatisfaction with the leniency of his sentence.
Minister Gerry Sutcliff is being dispatched to the US to investigate Megan's Law - with a view to similar law being introduced in the UK - tentatively titled Sarah's Law. This would enable concerned citizens to check via postcode if there is a known sex offender (including paedophiles) living in an area.
In addition Home Secretary John Reid has changed jurisdiction of Hostels where released offenders are housed to ensure that paedophiles are not housed near schools.
