...do they care? Is there a correlation between committing crimes and, for example, being on the no-fly-list? The TSA doesn't wait for a crime to interrogate you, send you back, download or bug your phone, and I'll eat my hat if they never planted child pornography on someone's phone to accuse them of a crime. If a CIA/NSA clerk once flagged you as a "person of interest" (and 3rd degree phone relationship with a criminal is enough), they'll find a good reason to accuse you.
