> But look at all the US kids having armed police sent to their homes because they swore on Xbox live.

I'm assuming you have links or evidence to back those claims up. Or are you mistaking this for kids getting swatted[1], because I certainly haven't heard of kids getting in trouble with police for swearing on Xbox live and I feel like that would make national news.

It's not because of swearing, it's generally because of a grudge.

Making false statements to police is not protected speech. In every instance of this happening that I'm aware of when police are able to track down the individual(s) responsible, they are prosecuted, generally to the fullest extent of the law. It's dangerous to make something like a murder/suicide threat, and it should be treated & prosecuted as such. Yes, the police probably overreact, but they don't necessarily know it's a hoax.
