I can't click on links because of my limited date allowance each month. I'm just going by your headline. Sorry, if what I'm saying has nothing to do with your link. A few years ago the high school (they call it gymnasium) my son and 3 of his friends own in Sweden was almost overtaken by some youths who had immigrated into the country. This was an armed young gang. The policed called and told my son they were there so he had time to lock the inner doors. They have a large covered area on the back of the building, I can't recall, I guess it's a parking lot and maybe they do sports out there or something in cold weather. The group (I think it was 5 or 6 young people) made it that far and into the first little entrance. They got the doors locked just in time. And now keep the school locked up all the time. My son is licensed to own guns there and was able to take my mom's antique rifle into the country. He isn't allowed to pack iron at work or probably anywhere in the country unless he's out duck hunting or something.
