i feel sympathy for the idea, but it kinda undermines the case against these practices. If we're saying "terrorism" isn't enough of a reason for wide-scale privacy invasion, how could "getting the US to change its policy" ever be enough? Additionally, it's an individual's rights being infringed, almost none of whom have influence on policy beyond voting, and the vast majority of whom, belonging to the subset of Americans traveling to Europe, didn't even vote for Trump.
