When I used to sell fake IDs and counterfeit credit cards online I always wore gloves and wiped everything down to be safe. You have to be especially careful with tape since it can pull a perfect print very easily.
The words "confidential informant" are prominent in the FBI press release. Almost to the point of being silly, e.g. "yet another confidential informant". Historically that has already been abused by law enforcement. Pervasive indiscriminate electronic surveillance will only make things worse.
I wish NSA, CIA, NRO et al would do useful things with all the billions they're spending. E.g. where is Malaysia Airlines Flight 370? Keeping track of airplane movements would IMO be a much more productive use of their resources than much of what they're currently doing.
