This is a different scenario though. With the area I am talking about in my country, the gangsters are well known by the community and police, as they should in daylight and they are people's neighbours. It is just that the police don't do anything or are corrupt. The criminals are known and therefore should be shot, because they are serial murderers and rapists. They can be easily caught in the act. To let them continue is to let the criminals thrive and the innocent suffer.
Being corrupt is a crime, too, isn't it? Do these cops deserve to be killed for their corruption, or only the gang members?
I think an important question that needs to be answered up front is, who gets to decide which criminal gets to live and which one is to die?
Regarding these gang groups, well known in the community, yes. If someone has been proven as being a rapist then yes too. Or at least castrated.
In this case, I agree with you that the law is probably insufficient, though not for the same reasons.. The impression I have of the kind of macho vigilante culture that tends to exert brutal violence on would-be criminals or suspects, is that they really enjoy to exact revenge on those who "defile" "decent" women, but often see few problems with violence against women they deem of lesser decency (usually sex workers and so on), or women who are otherwise deemed "untrustworthy" and thus unworthy to be believed (often the poor or marginalized). That is, at least, my opinion on the subject. In either the lawful or the vigilante system, the decision which woman to protect remains in the hand of unaccountable men who tend to judge arbitrarily and partially.
I don't view people as inherently evil. My points are to prevent further suffering by the innocent through eliminating the guilty. There is a chance that they could reform but I care about the here and now as opposed to a future possibility.
It seems very much that you believe certain groups of criminals, by virtue of membership in gang organisations, deserve death, while other criminals deserve to live. It is this arbitrary judgement that I am so uncomfortable with.
Why do rapist gangers deserve to get killed without trial, but not rapist cops or rapist millionaires?
Is it because they are a greater threat, or is it because they are at the bottom of the social order, and therefore disposable to a degree that cops or millionaires are not?
As for Rule of Law, and peoples whims, I am not talking about going around and killing people in random areas based on rumours.
This is the scenario:
I hear gunshots every night in the next door neighbourhood. People in the community know who are gangsters since the gangsters openly admit they are such and the people see them walking around as gang members. They see them shooting others. So these aren't mere rumours. Someone can just go undercover and confirm such things. Simple.
The current situation is that sticking to the rule of law in this situation hasn't been conducive to establishing just social order.
It seems to me as if you think a functioning justice system is irrelevant to a just social order. Do you think there is no use in following proper legal procedures when the criminals belong to these specific social groups? If so, why?
