Input: Consider Input: Kim Jong Nam is the exiled half brother of North Korean leader Kim Jong Un. Here he is pictured at Beijing airport in China in 2007.
As of 2003  he lived in exile in Macau and other neighbouring regions  after falling out of favour with  his father who accused him of turning "into a capitalist " according to an email sent to the editor of the Tokyo Shimbun by Kim Jong Nam . He said: "After I went back to North Korea following my education in Switzerland  I grew further apart from  my father  because I insisted on reform and market-opening and was eventually viewed with suspicion."
In 2012   Kim Jong Nam  heavily criticised  his  family's North Korean leadership.  He  said: "The Kim Jong-un regime will not last long. Without reforms  North Korea will collapse  and when such changes take place  the regime will collapse " according to excerpts from Japanese journalist Yoji Gomi in Tokyo Shimbun newspaper.
On February 13  2017   Kim Jong Nam  was about to leave on a flight to Macau where  he  lived with  his  wife and two children.
But  he  died on  his  journey. South Korea was quick to accuse North Korea of dispatching a hit squad to murder  him  at the airport in Kuala Lumpur  saying two female assassins poisoned  him  and then fled in a taxi.

Input: Consider Input: Kyle Enos  25   was sentenced to eight years in prison for selling drugs.
 He  traded fentanyl  a powerful opiate  for bitcoin to anonymous buyers.
 Enos  posted doses in envelopes at  his  local Post Office in South Wales.
Police released the text of  his  dark web sales pitch after  his  sentencing.
This is how  drug dealer Kyle Enos  attracted customers to  his  online opiate store  trading drugs for cryptocurrency on the dark web.
 He  traded in fentanyl  the powerful painkiller that can be 50 times as strong as heroin and which contributed to Prince's death  by offering customers supermarket-style "buy one get one free" deals in exchange for bitcoin.
Police also released footage from  Enos 's custody interviews  in which he describes how the drug operation works.
 Enos  told officers  he  did not make fentanyl himself  but ordered the substance in bulk every few weeks and sold smaller doses to individual customers.  He  used  his  local Post Office in Newport  South Wales  to ship the drug in envelopes.
They communicated anonymously over the dark web   he  said  in exchange for bitcoin. The footage does not give any sense of how much money  he  was making.
The text from  Enos 's storefront is in some ways very prosaic â  he  has a summary of delivery times  offers refunds and guarantees and emphasises the quality of  his  customer service.
However  the illicit nature of the exchange is also obvious from  Enos 's pre-emptive warnings about keeping receipts: Customers needed to be reassured that their information would not be preserved in case  Enos  were ever caught  which  of course  is exactly what happened.

Input: Consider Input: HAVANA (Reuters) - With revolutionary leader Fidel Castro dead and his brother Raul vowing to step down as president in 15 months  it will soon be the hour of heir apparent Miguel Diaz-Canel  an advocate for modernizing Cuba's state-run media and abysmal internet access.
 Diaz-Canel  was elevated to the position of first vice-president in 2013  putting  him  next in line for the presidency.
At 56   he  is a relative youngster in the ruling Communist Party's leadership and will need to appeal to younger generations if Cuban communism is to thrive beyond the Castro brothers.
 He  has already established press and internet freedom as signature concerns  a potentially disruptive change in a one-party state that has monopolized the media for nearly 58 years.
Otherwise  however   he  has a much weaker public profile than the Castros and it is not clear what policy changes  he  would push through.
Until now   he  has held to the party line or avoided public comment on key issues such as economic and political reforms or relations with the United States  which were overhauled by Raul Castro and U.S. President Barack Obama over the past two years.
Still  experts say  his  position as heir apparent is solid and that  he  would have to stumble badly for someone else to leapfrog  him  and become the next president in Cuba's arcane system for choosing its leader.
Born after the Castros took power in 1959   Diaz-Canel  is a child of their revolution who rose through the Communist Party by cultivating relationships within the political elite while avoiding the show-boating that ended the careers of other pretenders.
" He  has the advantage of having outlived  his  predecessors (as heir apparent) " Christopher Sabatini  a Cuba expert at Columbia University's School of International and Public Affairs  said on Monday.
 Diaz-Canel  has been careful not to eclipse Raul Castro and is so cautious as to come off as dull and gray   his  public statements largely unmemorable.
" He 's sublimated any ambitions  he  may have had  so the question is what  his  role and power will be among the old guard. Most people try to imagine  him  bridging the new generation and the historic one. That should be challenging " Sabatini said.
That reserved behavior and the government's secretive nature make  Diaz-Canel  largely a mystery to all but Cuba's political elite.
U.S. officials say they know little about  him   and most Cubans outside  his  hometown of Santa Clara know even less.
If  he  does take over in 2018   Diaz-Canel  will be following 59 years of rule by the Castro brothers  one who was gifted with abundant charisma and the other who commanded the absolute respect of top military and political figures.
" He  will be the first civilian president of the revolution and that will require the confidence of the military " said Arturo Lopez Levy  a former political analyst for the Cuban government whose mother taught Diaz-Canel at university.
 Diaz-Canel  chose to pedal.  He  would navigate the provincial capital Santa Clara  vying for space on narrow streets clogged with horse-drawn carts  motorcycle taxis and pedestrians.
