Swiss chainsaw attack "Not an act of terror"

[NotAllThere]

For it to be a terrorist attack you need to be doing it to further some sort of political agenda which has a visible leadership which supports the actions.

According to whom?

The FBI defines terrorism as

“the unlawful use of force or violence against persons or property to intimidate or coerce a government, the civilian population, or any segment thereof in furtherance of political or social objectives”.

In the UK, it is defined under law as:

“The use or threat of action designed to influence the government or an international governmental organisation or to intimidate the public, or a section of the public; made for the purposes of advancing a political, religious, racial or ideological cause; and it involves or causes:

serious violence against a person;
serious damage to a property;
a threat to a person's life;
a serious risk to the health and safety of the public; or
serious interference with or disruption to an electronic system"
