Sounds like Russians learned their lesson.

There's similar phenomenon in safety stats. In the stats Istanbul appears to be vastly safer than London but having lived in both, I can tell you why Istanbul is safer: Because public spaces don't exist and private spaces are guarded with bars and steel doors.

In London, there's pubs etc. everywhere, in Istanbul you are limited to few centers to be outside after 10. The places where people go are bustling because they serve a city of 16 million, so they are well lit and guarded.

In London, there are parks and guard free public spaces everywhere. In istanbul there are very few such places.

In London people mostly live in homes that don't have bars on the windows but in Istanbul there's bars on the first floor on every window on any building that's not a gated community. People with money live in gated communities or one of the very few upscale district.

In London you can walk ro everywhere, it has wide sidewalks and not many hills. In Istanbul sidewalks are tiny and often interrupted and the city has hills, as a result very few people walk more than a few hundred meters and people with bicycles are rounding error level non existent.

In Istanbul there's simply not many opportunities for crime, so when it happens it happens differently that the way it happens in London. No one ill grab your phone and run but if you wander in a non-commercial location or location that is not well lit after dark, you can be raped or stabbed just like that.

You can't really compare the realities of these cities by simply looking at some numbers without proper context.
