I agree he is brave and of course his pain and tears are genuine however I would question why a man from his background having just suffered as he has decided it was sensible to say what he said knowing that the media will now gloss over the reality that this was a madman and not at all representative in any way of other people who might disagree with what her political views are.
I did read this on another platform though which sort of ties into your part about the love aspect:
the Guardian headline, "Jo Cox's husband says she was killed because of her political views"
How could he know that? In fact he has no more idea than the rest of us. Instead he's using her murder as opportunity to paint 50% of the British people as being politically aligned with a crazed killer. This man served as adviser to Gordon Brown during the time when he was labelling citizens as 'bigots' for expressing concern about immigration. And if you're puzzled as to how he's got over his wife's death and has gone bandstanding for Bremain so quickly .... well just know that he left his £106K job at Save the Children last October following serious allegations of sexual harassment of women co-workers.
