Actually, I can say that the Swedish military and Stockholm's police force are fucking awesome, that's what I can say! They were so prepared and dealt with this so well! They were on the scene in no time, getting people to safety and making sure nothing else happened. They shut down the subway and commuter trains a-sap, and all possible second targets were evacuated or got much increased security.
Swedish media also dealt with it well. Sure, there were some unfounded rumours about shootings floating around that started on Twitter (which is why my boss refused to let us leave work until we were 100% it was just rumors), but over all we got up-to-date, vital information right when we needed it. We knew where to go and where to not go.
Also, all us regular civilian types used social media to help each other out. Stores made sure people had a safe place to go and that people's kids got dinner if their parents were unable to get home in time. People opened their homes to those who were stranded, arranging spur of the moment pizza parties. And as far as I've heard the local nazi scum are disappointed with how this attack has failed to drum up racism and islamophobia in the general public. I hope the nazis keep being disappointed. Fuck those guys.
I literally spent yesterday's "event" drinking soda with my coworkers, going for a long walk, meeting up with an acquaintance I hadn't seen in 3 years, having a beanburger, walking some more, waiting 40 minutes for a train to get me home, and finally going to bed at my home in Uppsala.
It's horrific that people were killed and hurt. But it's a comfort to know that the military, the police, the media, and just every other person on the street here are prepared for horrific things, and meet them with both skill and heart.
