Watched lots of news today. Read lots of news online after reading this thread.
Facts seem to be the "victim" was under reasonable suspicion of being connected to the bombing threat. He didn't stop when challenged. He ran to a train. He was shot.
Everything else on the thread seems to be speculation.
On a slight change, let's not have the media do the bad guy's int for them. There's already speculation in the media as to why the bombs didn't go off. When the authorities find the answer let's hope the media don't chase after it. "Wire a wasn't connected to wire b" says the media - "Good" says the bad guy, "I'll get that right next time"
