The OP seems to imply that somehow gambling increases illegal activities and gives the example of prostitution and the consumption of drugs, but what gambling does at best is to attract those kind of people because they know that the people inside the casino have money to spare, but gambling in itself does not increase those activities, those activities will happen anyway, however there are some crimes that could go up due to the influence of gambling, for example those that are addicted to gambling will probably steal money to try to feed their addiction.
Yeah I agree to this that gambling is responsible for the increasing crimes in the community. Nice and wise people will never gamble because they know the consequences of gambling. In my community a gambler has no respect even in his own home. He is just an idol person of the community. If he has a lot of money and no respect then he should think about his life.
I would rather say people are generally responsible for the crimes they commit and it has nothing to do with gambling at all. I understand just like the OP and so many people have said that it is a normal thing to see a lot of people associating criminal activities like drugs, weapon and ammunition dealings and the likes when it comes to gambling, but really, with or without gambling, that does not stop criminal activities from still taking place in a society.
I think what most people really have about casino is that a responsible person does not gamble and that makes it filled with irresponsible people who are prone to criminal and immoral activities, but that is a lie.
