Out comes the history books once again, we do no longer live in the 1800s, crime has increased in modern day England, due entirely to the increase in immigration, just has the shortage of housing, schools and the demise of the NHS, and don't come up with the old chestnut yes but what about the foreign doctors and nurses etc?
I admit that we are indebted to those, but we are not indebted to the mass importation of the foreign criminal gangs and killers that we have welcomed into our once more peaceful and law abiding country.
But if you still want to venture back into the 1800s or even into the 20th century, we knew what tio do with murderers back then, yes we removed them permanently from society.
Take the Jack the Ripper Murders in London, yes whoever he was he murdered a few women, but his crimes have gone down in history, or even Dr Crippen (who incidentally happened to be American) and who murdered his wife, that type of crime would not even reach the headlines these days of daily killings on our streets.
