rudie can't fail
1).Oft used line from legendary band The Clash used in "Safe European Home" and titular "Rudie can't Fail". A "Rudie" is an icon of its subculture with supposed powers invisible to the rest of society.
In FakeNews:- White skinned Ska rudeboys and rudegirls give their money to their darkest, dreadlocked, coolest, charismatic, usually drinking a beer, friend:- the Rudiest Rude - "Rudie". This "Rudie", they believe, has incredible ability to stumble upon contacts, commit crime like buying cannabis in UK, quickly, clandestinely, efficiently in any strange location, based on sub cultural prejudices. They just hand over their money, push them out in public, to do amoral work and believe, culturally, "Rudie Can't Fail!"

2)Strategy being used by Republicans and Donald Trump's Defence Team that Rudie Giuliani is their

"Rudie Can't Fail!"
"How you get a rude and a reckless?
Don't you be so crude and feckless
You been drinking brew for breakfast
Rudie can't fail" The Clash

"Rudie" so credible, even "normal" within the subculture, actually is quite visible to the general public as somewhat eccentric, entertaining, smooth talking, but certainly suspicious and activity worth reporting to the police.
US TOURIST "Ya know I gotta pal that can be dropped off outside any cantina in ELA - never been there before - we give him our money and in hour he's back, smiling, the best coke deal and we drive off. These total strangers look at his full body tattoos, knife scarred 400lbs and "big, beautiful eyes" and just trust him! Anywhere! It's really screwed up! - I wouldn't show my face in those neighbourhoods, Man!"
UK RUDEBOY " I gotta Ska mate like that - ironically - don't look like THAT though! - Any strange place, give him the dosh and that Rudie Can't Fail... Where's that mate of your's now?"
