In the news

Being arrested for writing even what he wrote is a travesty.

He could just be an attention-seeker and he could have made up the story, or the police may have acted on a complaint from the woman he allegedly spoke to. We don't know yet. Whatever, he's still a plank.

(I do think that a lot of people don't get arrested for what they ought to get arrested for, and some people get arrested just because something like this becomes high-profile, even though it does not warrant the actual arrest.)

Just for some important clarification, he wasn't actually arrested for the "mealy mouthed" tweet.

He was arrested for inciting racial hatred which was based on a number of subsequent tweets which where racially charged in nature and included one where he blanket referred to muslims as "towelheads".

Whether that was right depends on your views of the fine balance between freedom of speech and the right not to be discriminated against and abused because of who you are rather than what you do.
