It is disgraceful.
The comments calling it as disgraceful on the Daily Mail have hundreds of red votes.
If a similar distasteful joke had been performed and put on social media about Hillsborough, Lockerbie, IRA Bombings, 7/7 or something there would be uproar.
Unfortunately it seems that because the majority of residents and dead were immigrants (or descendents of and therefore not 'British') many people with right wing views simply do not care.
This country is becoming an increasingly nasty place. I'm ashamed to be British.
