> What I worry about is a few years down the road when all of this security state nonsense is used for political reasons.
Why do you think this isn't happening presently? Are you aware of the IRS's targeted scrutiny of certain groups applying for 501c3 status? This does not directly relate to the NSLs being discussed here, but it is an indication of how politics enters government agencies.
Frankly, I would be surprised if these NSLs aren't currently being used for political ends, by whomever has access to their use.
