Are tourists subject to these kind of foreign laws?

As long as you are in a country you are subject to its laws.

You are subject to the laws of the place you are in. Always. Where you are from has no bearing whatsoever.

You are ALWAYS subject to the laws of the jurisdiction where you are physically present. That is true in EVERY jurisdiction on the planet.

U.S. laws apply to everyone in the U.S. Dem furriners do de same. Seems obvious.

They apply to anyone. Even passengers on cruise ships who never sit foot on the country can be prosecuted if they engaged in prohibited acts while the ship is in port in the country.

Yes, absolutely.  Tourists and foreign residents are subject to the laws of the country they are in.

My friend's daughter (American) was a teacher in Qatar for many years but had to leave there because she wanted to have a child through sperm donation.   Being an unwed mother gets you thrown in jail in that country.

You can't send certain care package items to American military personnel depending on where they are stationed.  Alcohol, pork, etc. 

ANYONE in the country is subject to the laws of the country...so visitors to any country you have to abide by their laws, or be prepared to face the punishment

their country, THEIR laws ........................................

I don't know if it does, but it would suck if it did, or rather the tourist would suck and if they did they would get whipped and that would suck for them.

You break the law you pay the price
