The Walking Dead returned with a bang for its eighth season Sunday night  as Alexandria  the Hilltop and the Kingdom escalated the conflict with Negan and the Saviors to all-out war. Before leading the attack on the Sanctuary   Rick  delivered one of  his  classic impassioned speeches about the meaning of the group's mission.
"We found each other and that bigger world is ours by right "  he  said. "And if we've come together  all of us  it's that much more true. It's ours by right. Any person who would live in peace and fairness  who would find common ground  they're right too. But those who use and take and kill to carve out the world and make it theirs alone  we end them. We don't celebrate it. We don't have shame about it either. There's only one person who has to die and I will kill him  myself . I will."
However  there were also a series of cryptic flash-forwards interspersed with the present-day battle scenes that featured a much older  Rick  waking up in  his  home with Michonne  Carl and Judith followed by a wildly distressed  Rick  alone in an unclear location. "My mercy prevails over my wrath " the tearful  Rick  whispers near the end of the episode.
The old-man Rick sequence was teased in the trailer for the season that premiered at San Diego Comic-Con and led fans to speculate that the show intended to mirror the time-jump that takes place in the Walking Dead comic books following the war with Negan. But judging by the setup of the premiere  it seems more likely that it is only Rick's vision of what could have been if he and his family had been able to live in peace.

question:
South Africa's former police chief and ex-president of Interpol Jackie Selebi was convicted Friday of corruption for accepting bribes from organised crime.
 Selebi had denied the charges against him  which he said were part of a broader political conspiracy that reached to the top levels of government.
 The trial laid out his startling links with the criminal underworld  in particular with convicted drug smuggler Glenn Agliotti who was accused of giving him cash and luxury gifts.
 Selebi was accused of taking bribes from Agliotti totalling more than 1.2 million rand (166 000 dollars  122 000 euros) between 2000 and 2005.
 What finally emerged was a picture of Agliotti  who was also accused in the murder of a local mining magnate  indulging Selebi's fondness for designer clothing  which the police chief rewarded by feeding Agliotti inside information.
 While in office  Selebi acknowledged his friendship with Agliotti saying "Glenn Agliotti is my friend  finish and klaar (end of story)."
 It was Agliotti's drugs conviction that lifted the lid on Selebi's activities  sparking a lengthy investigation into his life.
 His first arrest warrant was issued in September 2007 but he was not charged  reportedly due to protection by then-president Thabo Mbeki.
 On January 11  2008  he was charged with corruption and defeating the ends of justice due to his friendship with Agliotti.

We had an excellent working relationship with  Commander Johnson . It was an honor and privilege to work with  him    he  attended our weekly deployment meetings  coordinated many emergency preparedness drills ...  He  was a true representative of not only the Northwestern University Police Department  but also law enforcement as a whole."
