I have to look up the redaction codes used by the DOJ. It may be because of Durham.

Edit to say: b7c is used to “protect personal information.”

The bigger issue, in my opinion, is all of the b7e redactions we are seeing.

Link to info on b7e exemptions

Additionally, in the current post-September 11, 2001 environment, law enforcement information that might be covered by the provisions of Exemption 7(E) should be viewed in light of its potential for causing harm -- or risking danger -- to individuals or to the public collectively.

In sum, law enforcement agencies -- including the wide range of agencies that discharge homeland security-related responsibilities (44) -- may avail themselves of the distinct protections provided in Exemption 7(E)'s two clauses. (45) Their "noninvestigatory" law enforcement records, to the extent that they can be regarded as reflecting techniques or procedures, are entitled to categorical protection under Exemption 7(E)'s first clause. (46) In addition, law enforcement guidelines that satisfy the broad "could reasonably be expected to risk circumvention of law" standard can be protected under Exemption 7(E)'s second clause.

I am not a lawyer, but this feels like a catch-all redaction code to keep the public in the dark

at the beginning it does state declassified "in part" by DJT and plus, you know important sources and methods are, bahahaha
