A Palestinian man  is summarily shot in this video.  Richard Silverstein describes the action on his website:

 . . . a mob of mostly ultra-Orthodox Jews pursuing a lone
Palestinian man and shouting repeatedly, “shoot him, shoot him.”  Then
police sirens are heard.  The video clearly shows the police car, the
officer exiting it pointing his weapon and killing the Palestinian.  The
officer never says anything to the victim beforehand.  He doesn’t tell
him to stop.  He doesn’t identify himself.  He shoots first and then
asks the crowd whether the dead boy stabbed someone.  Another Israeli
responds: “He hadn’t yet succeeded [in doing so].”   . . .
