No, he isn't joking.
London Mayor Sadiq Khan on Monday claims that cities cannot solve their crime problems through mass arrests — a claim that Khan has repeatedly made, even though he has never been able to back up the claims with any evidence.
“There is no place for crime in London,” Khan said on Twitter. “But we can’t arrest ourselves out of the problem.” adding “From removing knives from our streets, to providing young Londoners with meaningful and engaging activities, I am committed to being tough on crime and its complex causes.”
“We can’t arrest our way out of London’s crime problem,” Khan said more bluntly last year.
"It seems like basic logic has completely abandoned western civilization."
However, the Mayor of London's normal 'doublethink' has no evidence supporting it. In utter and devastating contrast El Salvador's president proved that arresting criminals does, as one might expect, dramatically lower crime rates.
El Salvador was in the grip of violent crime gangs and took the brave decision of tackling them head on: locking up every gang member they could find — nearly 2% of El Salvador’s population — and his nation transformed from the murder capital of the world to one of the safest countries in Central America. While the West accuses him of all sorts of human rights abuses (which they are guilty of themselves) — the fact is he now has a 92% approval rating — something Western leaders like Khan could only dream of.
Whatever human rights violations he may be guilty of, the fact of the matter is the average Salvadoran views the abuses of MS-13 and the 18th Street gang as infinitely worse. That said, we don’t have to look to Bukele alone for guidance. Former New York City Mayor Rudy Giuliani operated a zero-tolerance policy with great success, whilst Mayor Michael Bloomberg made crime plummet in their city using far less harsh methods through stop-and-frisk.
