This is why the government of some countries are working hard to make sure that gambling is banned in their nation because it causes a whole lot of alarming issues. Imagine waking up to such a disturbing news, I'm sure the people in the Philippines were perturbed by this. Gambling shouldn't be something that is supposed to resort to violence. I think they were under the influence of hard drugs
You shouldn't put the blame on gambling but on the evil people who uses gambling as a means to carry out their evil activities. There are decent people that gambles out there, but since gambling is open to all both the good, bad and ugly will be involved. The government of Philippines should make sure that all underground gambling room should be shut down. Maybe, put a strict regulations on casinos.
