No idea whether this is the right way to read it but it’s possible all the same:
Russian women suffering domestic violence are being deterred from going to the police since its partial decriminalisation last year, campaigners have claimed after a dramatic fall in reported incidents.
The state statistics, released in July, reveal that the number of cases of domestic violence reported to the police in 2017 almost halved since physical abuse became punishable by a fine rather than time in prison.
Controversial amendments to Russian law decriminalised some forms of domestic violence in February 2017. The changes mean violence against a spouse or children that results in bruising or bleeding but not broken bones is punishable by 15 days in prison or a fine of 30,000 roubles (£380) if they do not happen more than once a year. Previously, these offences carried a maximum jail sentence of two years.
A substantial number of such reports were punishment of the male because he’d pissed her off. Now the sentence is much less there’s no point in falsely reporting to inflict said punishment.
No, don’t think even I agree with that but it is still a possible explanation of events.
