Shooting from the fingertip

Labour’s health mouthpiece, I read, was forced to apologize after offering his condolences to the Liverpool hospital bomber’s family by mistake.
    Where do they get characters like that, who feel obliged to poke their noses in uninformed instead of taking the trouble to find out that the casualty was the mad bomber, not a valued member of the community?
    I suppose it’s the new normal. People are able to express an opinion instantly online and they don’t feel obliged to make sure it’s worthwhile before they hit the send button.
