Re: Rising tide of hooligans and mass attacks
Listen. . . You can't defend yourself empty-handed against 20 - 40 people with bad intentions. Frankly, even if you are a master with a sword, or have a good combat shotgun and know how to use it you aren't going to be able to win against those odds. The only thing you have going for you with a weapon is that it might shift the fear balance in your favor. If some of them know they will certainly die, they will rethink their desire to attack you.
Truthfully, this is not even a martial arts question. It goes way beyond that.
I don't know much about Malaysia, but my guess is that there are no real individual rights, private property ownership is not truly respected, and you have very strict guns control laws.
It wouldn't surprise me if your former peacefulness was due to very harsh and violent aggression on the part of your government to maintain it.
This is all speculation, but with the symptoms you describe, I'll bet I'm correct.
