Can you explain this?
Easy. This is what happens when you have a dysfunctional law enforcement.
The police is so corrupt that it is impossible no to take bribes, since at the end of the day you will be asked by your commanding officer to give your share. And if you want to be honest, you will be quickly "transferred" to some place else.
And with police mostly focusing on bribes, people know they can get away with a lot of things an d they have no problems violating the law.
This did not happen instantly, it happened with barely noticeable shifts over many years.
And even people, who tried to behave, eventually give up seeing how violators of the law are not prosecuted.
