Before criminal/blogger Martin Kok was shot dead last year there was another attempt the same evening, but the gun jammed.
At 6:40 you can see it.
There must've been a lot of background noise, considering Martin and his 'friend' didn't hear those footsteps or the gun jamming.
Also the people on the bicycles didn't notice anything. Sign of the times I think, everybody is in his/her own bubble with their phones/I-pod/headphones.
