But since the establishment of the USA PATRIOT (Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001), in Europe it is better to use materials that are not related to USA PATRIOT ACT because, according to the American legislation, the manufacturers have "opened" them ... for the American government ... and perhaps not only.
