Swede here, shit is BAD, but this is relative to how things used to be before this shit started, so in relative global terms Sweden is still a damn good place to live.
That being said, this behavior should be seen as a warning to not take culture clashes lightly.
I am sure I am going to catch a lot of heat for this, but damn it, it needs to be said.
The gangs we see are a direct result of a terribly run migration policy.
We have taken in far, far, far too many migrants in a way, way, way too short ammount of time.
This combined with a integration policy that keeps failing over and over as we continously refuse to enforce even the most basic attempt by migrants to integrate. There are many migrants who has lived in Sweden for many years without speaking either Swedish or English, they still have a right to free interpretors when dealing with doctors and government services, this is fucking mental.
We have punnishments and laws fitting Swedes from the 1960s or so, they don't do shit against the modern gangs.
So what needs to be done?
Start actually deporting criminals, log their DNA and give them a lifetime ban on returning, check all migrants against this database.
To those born in Sweden, start instituting extra long prison terms for criminals who keep reoffending.
Enforce learning the Swedish language and check compliance with in-person tests, and mandatory lessons. If you need an interpreter after 3 years, you have to pay for it yourself.
