"There's a security problem in Europe at the moment". What are you talking about? The number of people harmed in terrorism-related events in Europe in any given year is dwarfed by the number of people who harm themselves by accident or stupidity in those same countries. And dwarfed to an even greater extent by the number of people killed by police in the USA, or killed in mass shootings that don't get attributed to terrorism in the USA. It is the media attention given to the situation, not the situation itself, that is terrifying. Europe is extremely safe and does not have a security problem.
The entire western world has a problem with xenophobia. It can't control its own politicians who lead military assaults on middle eastern or north african nations for purportedly moralistic reasons. Assaults that are guaranteed to alienate entire generations of people and incite preditable retaliatory violence.
Nothing about the proposed privacy intrusions helps protect people from 'terrorism'. It feeds a cycle of ineffectual security theatre and provocation of western-produced radical activism that makes us all less safe. With one hand we create and promote terrorism, and with the other we strip ourselves of our freedoms and march toward technological totalitarianism.
