DHS chief Mayorkas says it's 'virtually impossible' to monitor all hate online

Homeland Security Secretary Alejandro Mayorkas told CNN on Monday his department is working closely with local authorities in the wake of a deadly mass shooting at a supermarket in Buffalo, New York, over the weekend, but noted DHS is not in a position of monitoring every American.
Asked if DHS should have caught the 180-page racist screed posted online and attributed to the suspected gunman, Mayorkas said: "No, because are we monitoring every expression of hate on the internet and social media? That would be virtually impossible."
Instead, Mayorkas argued the question is whether an individual who has been encountered by the mental health system should be able to purchase guns. State police had previously taken in the 18-year-old suspect -- who allegedly shot and killed 10 people on Saturday -- for a mental health evaluation following a "generalized threat" while he attended Susquehanna Valley Central High School, Buffalo Police Commissioner Joseph Gramaglia said over the weekend.

The governments of Mexico and the United States signed a memorandum of understanding on Thursday to fund and expedite several wastewater treatment projects in the Tijuana River basin. Untreated wastewater continually affects residents living along the river, which flows across the border from Tijuana and through several of San Diego’s southern neighborhoods.
