Why do some Saudi students abroad act recklessly?

Salim Sahab, Al Madinah A Saudi student, whose name I won’t mention here, was recently tried for murder in the United States. The judge who heard the case found the Saudi student guilty of reckless driving in a residential area that resulted in the death of a 15-year-old girl. The officer who conducted the preliminary investigation told the judge that the student did not show any signs of remorse at killing the girl. The investigation went on for four hours and the young Saudi man did not at any point say he was sorry for the accident. Shockingly, he collapsed during the trial and kept crying while covering his face with his arms so that nobody could see him. Most news reports that covered the trial said the young man did not even care to pull over and save the little girl. He ran off and returned to the scene to find that the girl had died. The Saudi Consulate in the United States appointed a lawyer to defend him. The judge set bail at $1 million and the consulate is expected to pay it. Why do Saudi students act recklessly and never think about the consequences of their actions? I do not understand why they cannot realize that the US is different. US laws state that pedestrians have rights and drivers should respect these rights and stop at pedestrian crossings. In simple terms, the right to live comes before the right for a vehicle to pass. The US court system is different from ours. It looks at the gravity of the crime. I remember that a Saudi man killed another while drifting in his car in the Kingdom; the only punishment he got was to pay blood money. This is similar to a vigilant driver who hits a man by mistake and kills him. In the West, the situation is different. While it is true that the death sentence is a remote possibility, a life sentence is a strong possibility along with compensation worth millions of dollars. I read a story of a young Arab man who was deported for running a red light although his father worked for an Arab mission in the US. No one is above the law. He was sent home within less than 48 hours. Unfortunately, drivers who run red lights here usually do not get caught and get away it.
