Friends and family of Bijan Ghaisar gathered on Jan. 26. (Toni L. Sandys/The Washington Post)

Kudos on the July 16 editorial “Eight months without answers.” This is not the first time an editorial has asked for answers in the death of Bijan Ghaisar, and I hope it’s not the last. As a free society, we cannot allow the blue wall of silence to impede the accountability for what appears to be a questionable killing. Please keep the pressure on those responsible for this apparent abuse of police powers. Civilization requires it.
