Helen Wilson was on duty tonight and received a report after 10 PM that a group of people were gathering to gamble here.
Nowadays, with Mahjong parlors all over, they are generally left alone. Although gambling is illegal, the stakes within these parlors are typically small, almost seen as a form of entertainment. Therefore, the local police stations tend to turn a blind eye unless there is a report, in which case they would take no action.
But today's report indicated that the stakes were very high, and Helen couldn't ignore it, leading her to specifically bring six police officers to handle the situation.
Cracking down on gambling is usually routine—people caught are simply relieved of their betting money and fined. There's rarely any resistance, so Helen and her team were quite relaxed, not even bothering to carry guns, with the intention of covering all exits to prevent escapes.
