There's no dispute on whether Jesus Mesa Jr. killed 15-year-old Sergio Adrián Hernández Güereca.

He did. And there's a video of it.

In 2010 Mesa, an on-duty U.S. Border Patrol agent who was at the border in El Paso, Texas, shot Hernández at least twice — once in the face. At the time, the boy, a Mexican national, was on the southern side of the border in Ciudad Juarez.

Federal aviation regulators issued a new round of safety fixes for Boeing's beleaguered 737 Max jetliners, mandating repairs to sections of the planes that could make them vulnerable to lightning strikes and other activity which might result in engine malfunction.

The proposed fix issued by the Federal Aviation Administration on Tuesday said certain panels on the planes, including the metallic layer that serves as part of the shielding for aircraft wiring, is susceptible to potential "electromagnetic effects of lightning strikes or high intensity radiated fields."

Irresponsibility — by carmaker Tesla and by a Tesla driver — contributed to a deadly crash in California in 2018, federal investigators say.

The driver appears to have been playing a game on a smartphone immediately before his semi-autonomous 2017 Model X accelerated into a concrete barrier. Distracted by his phone, he did not intervene to steer his car back toward safety and was killed in the fiery wreck.

But Tesla should have anticipated that drivers would misuse its "autopilot" feature like this and should build in more safeguards to prevent deadly crashes.

President Trump criticized remarks by Justices Sonia Sotomayor and Ruth Bader Ginsburg as "inappropriate" and said the Supreme Court justices should recuse themselves from cases involving the president.

"I just don't know how they cannot recuse themselves for anything Trump or Trump related," Trump said Tuesday in a wide-ranging news conference in New Delhi.

"What Justice Sotomayor said yesterday was highly inappropriate," Trump added. "She's trying to shame people with perhaps a different view into voting her way."

True story: This past Valentine's Day I was walking out of the office when I overheard a group of younger colleagues saying that they were staying in to watch the sequel to Netflix's To All the Boys I've Loved Before, called P.S.
