It's my traditional English background. The use of a surname without a title or Christian name was reserved for Lords,but that seems to have gone by the bye.
Oh... Really.. I was thinking modernity is only visiting the African Society.. Haha.
I guess your good old days huh.
The other use comes from references by public school boys, who tended to use surnames rather than Christian names. (remember that in England "public" schools are the top private schools, free education is provided by state schools).
Like the youths are surely the leaders of today unlike the previous saying; Leaders of tomorrow Lol
I support capital punishment in cases like this if guilt can be proven without a reasonable doubt.
I support it too when confession is not induced.
