Regarding the Dec. 28 editorial "A curtain of silence":

Again, our community is diminished by the lack of transparency on the part of law enforcement. One can't help but think the officers are in the act of shielding themselves and creating explanations for why they shot Bijan C. Ghaisar. But if I were a lawyer, I would argue that his relatives should have equal access to information so that they can form any legal challenges to the actions of police and others. That would at least make it a balanced equation. This can't be the concept behind "investigations" — that one side would have all the pertinent information and the other, and most affected side, none.
