And as such it would be a random act of violence. What difference does it make that he had the same motivation as Fatah or Ilamic Jihad or Al-Qaeda? I would bet on a thread about hate crimes you would be arguing that motivation or intention made no difference. The victim was just as dead.
There is nothing that could have been done that likely would have prevented a loan gunman who didnt blab his intentions to the world from being able to pull off something like this.
No an action motivated by the terrorism is still a terrorist action.
