stun guns are illegal in sg and you need to bring 4? shows what a coward you are.
That's why I said cowards like you will shiver and pee in your pants when confronting the laws. I keep 1 in my car, 1 upstairs, 1 downstairs and another for spare. If I'm like you, this illegal, that illegal, scared of the laws, KNNCCB, how to carry on living in this world? Right or not bastard? You really no balls lah, everything also scared, like as if the Police is coming to knock on your door tonight.
When I was in Cambodia, they even offered me a gun as they said: every car in Cambodia has a gun inside for self-protection. They told me that they have some used ones and I can take 1 (with some bullets supplied) if I want, but I'll have to settle the "importation" by myself although they can guarantee a safe passage out of Cambodia for me.
