Oh dear...
While those that believe we are seconds away from a terrorist state... on here will probably cheer the reality is its massively catch all legislation and could severely curtail free speech...
However I would see if the ruling was used to curtail valid protest.. if the case was taken to EU law then there could be issues.
The problem here is that terrorism is a multi-facited problem - it's not just fearing for your life or the life of those that depend on you but also being targeted for the belief you hold.
War on the other hand is the application of military action against a state or people are part of the construct.
Is a anarchist flower bombing politicians terror? It's not a military action, it's civil unrest and a protest, however if the person has to fear for their life (it may not be flour these days) then is it terror? The distinction is if the flour is actually a substance that would cause injury or death - not injure their pride or appearance. Until that has been tested - it's unknown/undecided.
Is the demonstration of legal or police ability to oppose someone speaking their mind an act of terror? Again it depends if if that speech is to cause injury or loss of life.
As soon as the government are proven to abuse, for non 'terror' reasons, this then the law and those that implement it are then discredited. UK prides itself in being a shining example of how a government should operate (it makes money by providing consultancy in a lot of areas on that!).
Government is a civil & military system, with politicians, the system will take steps to ensure it's continuation.. for good or bad.. regardless of which political party is at the helm.
