In the United States, we enjoy a great number of rights when it comes to legal issues. Still, there are many incidents and complaints about excessive force by the Police and it being a police state where we have no rights. While our justice system leaves much to be desired, we still have some rights that we can utilize. For example, our right to remain silent, and having a sentence that is not too harsh for the crime (exceptions).
When you take a look at Brazil, they have zero tolerance for criminal activities there if the cops were to witness it. They will use deadly force at a whim, and that is because the crime there is so rampant. To stop a large fire, you must have a powerful enough hose, or it will become out of control.
