So "I would like it if someone drowned him" is fine, but not "I will drown you" (which was what was tweeted). Also, surely if he did get drowned after someone suggested it that would also be a crime of inciting violence?

Maybe the distinction is more complicated... I might need two tweets. Incitement is a tricky definition, because it's really an urging of something rather than something passive - it's almost an incentive. I am not sure how British law defines it specifically and can't be bothered to look it up.

I think your second example sentence would fall under that, even if no one actually carried it out, because it would be an enticement for anyone who wanted to please you and shared your thoughts. But if he was going swimming in the Bahamas, or something, and you tweeted "if he drowns out there, I won't be too sorry", that shouldn't fall under incitement and doesn't suggest any intent for yourself or others.
