Swearing is protected under freedom of speech, TV shows have some leeway as seen by South Park and Family Guy but that is thanks to the broadcaster, rating system and hours.
Formal shows like news reports aren't allowed to curse at all. They need to be professional.
Let's not forget that groups like the Westboro weirdos are allowed to say their opinion and are protected under the government.
Freedom of speech end when you make calls to physicaly harm people, you cant make death treats. So you cant promote voilence towards muslims. And for example southpark episode 200 and 201 got banned because they had a cencored muhhamed while a danish artist was allowed to make that infamous cartoon with muhhamad and a bomb on his head.

this is a dutch comedian singing on the memorial for Theo van Gogh (dutch director who made the infamous Submission) about freedom of speech. This was an official event attended by important people and broadcast on national television.
You probably dont understand it but its full of dirty words and mocking of religion while hailing the freedom of speech.
This my friend is true freedom of speech.
