That's ridiculous. Was it in good taste? No. Should he be arrested for it? Also no what the fuck
From the article:
“The man was arrested on 1 November on suspicion of a number of offences including using a public communication network to send offensive messages.
Should this be a law? Probably because people are dicks.
Should this guy be arrested using this law? I suppose it's different from charging them (and securing a conviction) and gives them time to investigate but this was a very traumatic incident (my uncle lives in Manchester and it had a big impact on him) so making a joke about it is offensive.
I get that it's offensive, I truly do, but I don't think people should be arrested just for being offensive. If he was threatening to do something similar or something like that, then that's different.
It's a difficult one for the police - sending offensive communications is an offence, and this counts as one, so they are duty-bound to investigate it. As unpleasant as it is, I hope it goes no further.
