The New Zealand Shootings

The Christchurch shooting happened in March 2019 and I had only totally disassociated from it until November 2018. The goal of blaming illegal aliens for the Christchurch shooting because of illegally immigrated Australian in New Zealand is pretty fucking remarkable. Condolences to the victims of the New Zealand shootings. So many pious folks lost because of psychotic rage. It is a sad thing that the mentally infirm can have access to guns. At no time after this terrible tragedy, did the United States Postal Service consider censoring the mail in order to stop announcements of terrorist or violent threats?
