I have no idea why you would guess that Russia has no passed out junkies its towns. Singapore and Rodrigo Duterte's Philippines have the sort of law enforcement you seem to admire.
Years ago I knew a chap who'd migrated from Singapore to Austalia as a schoolboy, probably around 1960 or a bit later.
He told me that when Lee Kuan Yew took over the government of Singapore in 1959, the gangs in Singapore made the New York gangs look like boy scouts. His father sent him to Australia to get him away from the gang warfare. As a middle class kid he was always being picked on by gang members from the surrounding slums.
But he didn't like Lee Kuan Yew as he lost a couple of friends due to his ruthless methods. The gangs mostly used knives and machetes but didn't have many guns. One of Yew's policies was to send in police squads dressed like gang members. They'd start a fight, and when gangs got involved they started shooting. He also introduced the death penalty. Apparently Yew was impressed by the lack of crime when the Japanese occupied Singapore in WWII as they ruthlessly suppressed criminal activity.
So when he got in power he did the same thing - treated crime harshly.
The chap I knew used to act as a lookout on smuggling boats to or from Malaysia. Customs were on the take, and some token boats were sacrificed to give the impression that they were doing their job.
Lew Kuan Yew inherited a criminal state, and cleaned it up. The hardline policy towards crime, drugs and murder that Singapore has today is a continuing result of his legacy. It is also quite prosperous, despite having very little in the way of natural resources. It has made use of human capital.
It's population density is about 8,400 people per square kilometre, one of the highest in the world.
