If teachers cannot do the job without breaking the law (Constitution = Law) or if they cannot handle the criticism which comes with being public servants (paid for with public funds) they should quit and go work for the private sector and see how THAT goes!
I have visited Saudi Arabia at least 20 times and never had a problem, however I would be concerned about visiting the US.
Saudi Arabia is quite open (righteous?) about its restrictions, unlike the US which appears to be a democracy but by many accounts seems to behave like a police-state. The other important difference is that Saudi Arabia does not have the influence on the rest of the world that the US does.
Professionals like lawyers, accountants, doctors, etc often pay a hefty price for bad decisions, negligence, etc. What are the consequences for judges? (Hypothetically of course - I would not dare suggest that an actual judge had made a bad decision - it is probably illegal :) )
Is it defamation...for a lawyer? If I wanted to hire a lawyer as an attack dog, I would WANT the biggest a*hole in town! Sadly I can envisage a situation where lawyers might actually use their position on a troll page to get business...
