I'm sorry because I think I was making fun of a serious question. But I think it's because I'm getting quite tired of reading often the same questions coming back from anywhere. It feels like most of people living with a "citizen mentality" (there is no despite in my words, just trying to picture the situation), especially in western world (as far as I'm concerned) are sooo dependant to State institutions (also because they desperatly trust in it, even there is no reason to do so) that they almost forget they can fight back if they are attacked, they can kill if they reasonnably think someone's threatning their lives, etc. It feels to me that we are often reduced to be like domesticated big sad dogs who would just have forget we have teeth, and that we can incidentally use it when we feel it's necessary.
That being said, I'm also not a "dogmatic" anarchist, and in the risk of choking some people right there, I don't think that "calling the cops" is the worst thing that can happen ever. I would say that I would highly advise against calling them in any possible situation, but in very specific case : when it's this or being killed (for example), I couldn't juge someone who did it : especially if it's a comrad, or someone I know would not have done it if there were any other possible solution. As I'm against prison, but also against people letting themselves killed or even being threatening of death...
I don't want to talk about specific situations or give exemples because I guess anyone can picture him/herself how you can find yourself in such a situation.
And I also hate the fact that some people are using the fact that most anarchists or even "simple people" who just hate the cops won't ever call them to commit abuse or threatening. IDK if you see what I mean, but to me it's a known fact that scumbags viciously benefit of the temporary disorganisation of poor people, and of the hatred of police so as to behave like little capitalist scavengers : looting you, beating you, exploiting you, killing you.
Of course it's not the police that's going to put an end to this. I think that it should be intersting to think about something like a form non-authoritarian collective selfdefense. I'm not suggesting anything like "militias" or leninist-alike stuff like this but I'm thinking of an exemple I was told by a friend who used to live in greece.
In the district where they were living, there is a lot of revolutionnary, anarchists and anti-authoritarians, and so they basically organize several open assemblies every week. Of course these assemblies were (and maybe are still) discussing about problems concerning social struggles and stuff, but they also were opened to daily life problems people face. So basically, a friend was regularly threatened and harassed by someone living in the building. So they just decided to make a group of people to go talk to that guy and told him that if he didn't stop, he was going to be in serious trouble. And then the friend never heard about him again. I'm not feeling very confortable with any kind of "popular justice" practices, but I think it's an intersting alternative to calling the cops when you can't defend by yourself. The think is that it requires a bit of organisation and strong ethics. By that I mean trying to priviledge de-escalation techniques rather than transforming any conflict into a little civil war.
