I don't buy the 'incredulous' response to suggesting that mens' freedoms be curtailed to deal with this problem as opposed to women's. As though it's just too much a response. Bollocks to that.
I live in an area that, years ago, was over run by gangs, groups of male youths intimidating people in the areas they 'hung out', organising 'running battles' between rival gangs, drug dealing on known corners etc. This problem troubled the authorities for years. Then, the police, youth charities, the local authorities all worked out a series of measures to tackle the problems. The police 'ring fenced' a large exclusion zone, in the main areas these gangs hung out, which meant that anyone who was found in groups of more than 2 people were 'rounded up' and taken away - they were taken to areas that were specifically set up to deal with them - various centres/clubs/organisations which then addressed the reasons these young boys/men had nothing better to do than 'hang out' in gangs, committing various crimes. They were offered the chance to do things they wouldn't have had the chance to do - sports, study, recreational activities that also came with training opportunities etc.
It was a massive undertaking, the resources it took were not inconsiderable, but you know what? It worked. Liked a dream. My area has never returned to being that place where gangs of young boys/men could 'hang out' or organise mass gatherings to have 'fights' or running battles, intimidate locals or local business etc. Lots of clubs that were born out of this initiative are still going, still giving the disenfranchised youth an alternative to the criminal life they would have chosen instead.
Why can't authorities who have these particular problems with large groups of young men to deal with,who are participating in these horrific attacks, curbed from gathering in such numbers? If there are resources being funnelled to deal with the massive influx of immigrants, why not include these sort of measures to address this trend? The fact that these gangs of men are targeting women/girls in this manor doesn't mean their actions/behaviours/cultural beliefs cannot or should not be addressed & specifically targeted with giving the police the right to 'round up' these groups & then deal with the criminal activities as well as address the cultural beliefs that would appear to fuel such behaviour - the Norwegian efforts to address these cultural issues would be entirely appropriate in these circumstances IMO.
