commented that the murders were "the most heinous crime to have been committed in this country for a generation or more". Reactions The murders caused outrage in the United Kingdom and there were calls for the reintroduction of the recently abolished death penalty and for an increase in the number of police officers trained to use firearms (British police officers are normally unarmed). The Metropolitan Police Firearms Wing was established soon after the incident. Six hundred Metropolitan Police officers lined the route of the three victims' funeral procession in Shepherd's Bush and a memorial service in Westminster Abbey was attended by Prime Minister Harold Wilson, Leader of the Opposition Edward Heath and many other dignitaries, as well as thousands of police officers from all over the country.

His flatmate was a heroin abuser and police ruled out any connection between his murder and the events of 1966. It was reported in February 2009 that Roberts hoped to be freed from prison within months. After serving 42 years, and having already completed the first stage of a parole board hearing, he believed that his release was imminent. Roberts hoped a final hearing would find that, at 72 years of age, he was no longer a risk to the public. By this time, he had already served 12 years more than the minimum term recommended by his trial judge, who at the time of sentencing told Roberts that it was unlikely that any future Home Secretary would "ever think fit to show mercy by releasing you on licence... This is one of those cases in which the sentence of imprisonment for 'life' may
