Frank Fu-yuan Huang, professor of crime prevention at Police University, explains, "Criminal psychology describes a phenomenon common today as the 'weapon effect.' Weapons make people feel powerful which causes them to become more aggressive." Behind the wheel of a car, for example, people are more apt to go berserk. Knowing that they can radio others for assistance makes taxi drivers more likely to provoke others.
「犯罪心理學裡，有一種『武器效應』，當一個人身邊有某種武器可以壯大自己的時候，攻擊性就會增強，」警察大學犯罪防治系教授黃富源指出，譬如開車時特別容易發怒激狂，或是無線電車隊司機敢於挑釁，都在於車子、無線電讓他們無限壯大了。
