(CNN) When a man snatched a wallet from a passerby's hand   Tess Aboughoushe  ran after him. When  she  caught him   she  invited him for coffee. Why? Because the Canadian woman felt it was the right thing to do.
It was February 14.  Aboughoushe  was heading back to work from the chiropractor in downtown Edmonton  Canada. The mugger had asked another woman for money and when she pulled out her wallet  he grabbed it and ran.
"I saw the man and the woman on the side of the road and as I was walking past  she calls out that her wallet has been stolen. 'Stop! Thief!' Legitimately  just like a movie scene "  Aboughoushe  told CNN. "He was running in front of me and I didn't really stop to consider personal safety issues."
 Aboughoushe  chased him down a couple of blocks  briefly lost sight of him and found him behind a dumpster in an alley.

H.R. McMaster  U.S. President Donald Trump's national security adviser  said at the Munich Security Conference that the federal indictments showed the U.S. was becoming "more and more adept at tracing the origins of this espionage and subversion."
"As you can see with the FBI indictment  the evidence is now really incontrovertible and available in the public domain " McMaster told a Russian delegate to the conference.
 McMaster  also scoffed at the suggestion that the U.S. would work with Russia on cyber security issues.
"I'm surprised there are any Russian cyber experts available based on how active most of them have been undermining our democracies in the West "  he  said to laughter. "So I would just say that we would love to have a cyber dialogue when Russia is sincere."
