If you decide to use a self -defense weapon, you should not pull with it. You need to do everything quickly and confidently. No need when you already got the weapon to start threatening the hooligans. If you decide to apply threats, hoping that hooligans will see your weapon apologize and leave in vain. On the contrary, you risk getting on the head with some heavy subject. Therefore, they took out a weapon of self -defense and immediately put it in.
