Sweden. It's pretty peaceful in general. But I just got unlucky and ended up growing up in one of the, at the time, worst neighbourhoods in the country.
Now the last troublemakers around decided to join up and formed a gang. But the police is doing their best to sunder them.
Sweden (or Norway ?) is scary
Best self-defence style is to do whatever the big guy ask you to do and not resist at all, IMO.
Fuck that, get a knife and stab his fucking eyes out.
This.
Really, these people are in it to pick fights and beat up the weak. You aren't getting out of it unharmed because they don't want you to. All you can do is fight back the best you can.
Lucky for me, I'm a big guy. Usually any wannabe gangsters know I'm not worth it.
