Dave,
I haven't suggested any inadequacies in anyone.

You did not juts try to claim, wrongly, that it was racist, you said of me, "And you know all about Manchester gangs do you Keith?"
" You really do live in a different world don't you."

No need for all that shit in an up to then friendly discussion.

Jim,
Where does it say his was the friend who his sister claimed was the reason

From your own link Jim,
"A family friend also alleged that it was the murder of Abedi's teenage friend that caused him to kill.
The teenager was run over and stabbed in Manchester in May 2016 in what is believed to have been a gangland killing."

And,
"Such anger was reportedly heightened when one of his friends, 18-year-old Abdul Wahab Hafidah, was murdered in the Moss Side area of Manchester a year ago."
