When is terrorism NOT terrorism

The term "terrorism" is used to describe the use of violence against non-combatants to achieve political or ideological aims.
It is a tactic that aims to instill fear and insecurity to influence decision-makers and prompt policy changes. Different definitions of terrorism emphasize its randomness, aim to instill fear, and broader impact beyond its immediate victims.

The United Nations Office of the High Commissioner for Human Rights (OHCHR) notes that while declarations and resolutions have articulated some distinct conditions and core elements, no standardized definition of terrorism exists internationally. The High Commissioner for Human Rights calls upon States to be guided by the key elements of acts of terrorism provided in Security Council resolution 1566 (2004) and the model definition developed by the Special Rapporteur. As a minimum, terrorism involves the intimidation or coercion of populations or governments through the threat or perpetration of violence, causing death, serious injury, or the taking of hostages

Assistant Chief Constable Jenny Sims of the Merseyside Police now says that they believe the driver of the car was able to access the road after following an ambulance that was attending to a member of the public who was having a suspected heart attack.

Access on Water Street, which was blocked she says, was temporarily lifted so that the ambulance crew could attend to that individual.

As with all large events we have armed policing presence throughout the day. There was no intelligence that an incident of this nature would take place - it is not being treated as terrorism.

Definition vs Described As
The terms "definition" and "described as" serve different purposes in language and communication.

Definition: A definition is a statement that explains the meaning of a word, term, or concept. It provides a clear and concise explanation that helps to establish the boundaries and characteristics of the subject. For example, the definition of "description" is "an act of describing; specifically : discourse intended to give a mental image of something experienced".
Described as: This phrase is used to convey how someone or something is characterized or portrayed. It often involves providing specific details or attributes that help to paint a picture or give a sense of the subject. For example, "She was described as having 'fierce blue eyes'".
In summary, a definition aims to clarify the meaning of a term, while "described as" is used to provide a detailed account or portrayal of a specific instance or characteristic.
