I would not call Saudi Arabia a police society. However, I will say that the police, Muttawa and other security officials have broader range on the actions or questions that can be asked of both Saudi and non-Saudi citizens. For the Saudis, there is both a respect and a fear of officials. The popular show Tash ma Tash has had examples of misunderstandings with officials. While Tash ma Tash depicts misunderstandings in a comedic way, such encounters are usually anything but funny.
As a result, many Saudis may cower to the officials. A corrupt official may take advantage of this.
When a Saudi comes to America for the first time he will likely have respect and fear for security officials. Some security organizations may take advantage of this cultural trait. A security organization may knock on a Saudi’s door stating they’d simply like to talk to the Saudi and learn more about their culture and Islam. Most Saudis will allow the official entry to their residence and answer the questions never realizing that they have a choice. If an official contacts a Saudi without a legal warrant then the Saudi has every right to decline answering any questions. There is no obligation or law requiring him or her to do so.
A law abiding Saudi is entitled to privacy and freedom of choice of who he or she speaks to.
Let’s face it, once a Saudi starts talking to an official, it is likely only a matter of time that questions would become more detailed, specific and focused. Now if a Saudi wants to talk about his friends and contacts and observations within a mosque for example, then that is his choice. But again, there is not an obligation. It is a choice.
If an official tries to pressure a Saudi to talk about specific subjects during a “friendly visit” a Saudi has every right to ask that official to leave. The Saudi can then notify local authorities and the Saudi embassy about the incident.
