I'm getting the impression you're a bit of an idiot.

A death threat is an offence in America too, you muppet.

Let's try this again:

"In Britain, tweeting messages considered menacing, offensive or indecent can lead to prosecution."

Now try reading that again slowly without mouthing the words. Not only is death threats an offense in Britain, so is tweeting anything that can be construed as menacing or offensive apparently. I'm surprised your government lets you breathe without its permission.
