Do you think mass arrests are impossible? Remember what happened in Saudi Arabia in 2017?
"As many as 500 people were rounded up in the sweep. Saudi Arabian banks froze more than 2,000 domestic accounts as part of the crackdown. According to The Wall Street Journal, the Saudi government targeted cash and assets worth up to $800 billion. The Saudi authorities claimed that amount was composed of assets worth around $300 billion to $400 billion that they can prove was linked to corruption."
