Translation of the leaflets they gave out beforehand:

Enough is enough! Sweden isn’t what it once was and no one could have missed that by now, and practically every day we have to wake up to news about new murders, robberies, rapes and other crimes.

We’ve had to suffer through innumerable cases of serious crime where the criminals never even get punished by claiming that they’re below 15 years of age. Around the country we’re getting reports that the police can’t combat this wave of crime targeting the Swedish people.

In some cases as in the murder of a woman, working at a home for unaccompanied refugee children, in Mölndal, it all goes so far the the chief police officer shows greater sympathy for the murderer then the victim. That type of respectless behavior is nowadays so deeply rooted in our spineless politicians, our weak law enforcement and our lying media that nothing surprises us anymore.

But we refuse to accept the continued rapes and harassment targeting Swedish women. We refuse to accept the destruction of our once so safe society. When our political leaders and police show greater sympathy for murderers then their victims there’s no longer any excuses to let it all happen without protest.

When Swedish streets no longer are safe to walk for swedes it’s our duty to do something about it. Today, 200 Swedish men gathered to send a clear signal to these Moroccan “street children” that’s ravaging around the central station. The police have clearly shown that they lack the means to repress this phenomenon and we now see no other alternative then handing out the punishments they deserve ourselves. The law enforcement have left walk over and the social contract are therefore broken – that’s why it’s the duty of every Swedish man to defend our public spaces against the imported criminality.

We who gathered today we’re not your politician, your journalist or your police officer. We’re on the other hand your father, your brother, your husband, your friend and your neighbor. Swedish men and women deserve safety in their everyday life and therefore we encourage everyone who also sees the problems to follow in our footsteps, both in Stockholm and in other places across the country.
For a better future together.
Also, be careful getting too emotionally involved with the term "children" in stories like these. This description includes anyone who claims to be 18 or younger, and there have been several, several, several cases where they've proven someone who said they were <18 was really >25. It's kind of how like they keep saying these immigrants, er I mean refugees, are mostly women and children, but all reliable sources are saying they're more than 80% grown men.
