Maybe he had an “allergy” to bomb making materials.
This is a narrative to divert motive. Valium would calm him for his murders, Do not let them avoid revealing the motive. There is strong indication of isis or hatred of conservatives. They are trying the Russian ploy to claim mental illness. That is a given for any murder but why did he plan this for the better party og a year. Who helped him? where did he get the explosives used by terrorism in NYC. This is a red herring. They know and the are not telling us to keep us from reprisals.
