I do honestly think that! Yes. And I do think that many european governments allowed those criminals and terrorists to enter Europe and spread chaos then use it as an alibi to increase surveillance and give the police and the state more powers. In my view European immigration policy is a total failure if people have to live in constant fear. Europe has to stop conniving with States that support backward ideologies like Turkey, Qatar, Saudi Arabia, Iran etc. There are good people in each of those countries that need support there, their numbers is growing they risk jail time or even their lives to enlighten their people they want a secular state, tolerance and democracy, the European Union should invest in them and help them and pressure governments to protect them.
