I’m a climate scientist. Let me fix this headline. “Nearly a century ago, scientists showed that burning fossil fuels warms the planet. Today, we know human emissions account for over 100% of the warming. Yet dark money and disinformation still work to keep Americans addicted to fossil fuels.”

This is a legitimately great idea. Turn every ICE concentration camp into a museum of their crimes and the people who fought against them.
In her letter to lawmakers, Thompson asked for help to close the facility and transfer its ownership from the federal government to the village for redevelopment as a museum. The “Broadview Justice Corridor,” as she called the project, would turn the ICE facility into a “national center dedicated to immigration history, civil rights education, civic leadership, and cultural tourism.

“This transformation would convert a site associated with fear, protest, and division into one that promotes education, reconciliation, and national dialogue,” Thompson wrote in the letter, estimating the proposal would draw up to 250,000 visitors annually and generate up to $31 million in economic activity.

“A Haitian asylum seeker held for four months died Monday at a Scottsdale hospital due to complications from an infected tooth.” It seems the infection spread from his tooth to his lungs, and he developed the pneumonia that killed him. In other words, ICE allowed a prisoner to die of a toothache.

This is very good reporting that sheds light on just how small the extremely pro-Trump online right really is. The online right is totally astroturfed. The White House's own staffers are running meme accounts to make them look more popular than they are. www.wired.com/story/a-whit...
But this isn’t just a regular account. Johnny MAGA appears to actually be a White House staffer named Garrett Wade who works for the Trump administration as a rapid response manager, helping to run the very same White House account his anonymous MAGA account amplifies. A phone number associated with Wade is linked to Johnny MAGA, according to a WIRED review of publicly available records, and the connection was confirmed by a source close to the White House.
Wade and the White House did not respond to requests for comment.The Johnny MAGA account was created in September 2021, according to its X profile. (It originally used a different handle, which referenced Wade’s birth year, according to records reviewed by WIRED.) While the account’s earliest available posts focused on NFTs, it has been a consistent pro-Trump presence since at least 2022.
The operator of the Johnny MAGA account has not disclosed an official relationship with the White House while operating the Johnny MAGA X account. Multiple media outlets, including Mother Jones, TownHall, and the New York Post, have all linked out to posts on the Johnny MAGA account seemingly as organic reflections of public sentiment on political issues.

They raided the jailed children to steal their letters. The problem, in federal officials' minds, wasn't confining children in prison-camp conditions; it was that the children could tell the public about it.

ICE has now spent over half a BILLION dollars just on purchasing warehouses around the country to convert into detention camps. If these mega-camps are utilized to the full capacity ICE intends, they'll be the largest prisons in the country, with little real oversight. www.ajc.com/politics/202...

ICE is a paramilitary force deployed in a campaign of state domestic terrorism. If the primary focus were immigration enforcement, they’d be raiding agricultural and hospitality industry settings. Instead, they’re going into residential neighborhoods, schools, and courthouses. Terror is the goal.

Something that is very important here is that this man’s fellow agents didn’t rush to help him or save his life, barely even pulled over. This is not a military unit joined by bonds of brotherhood and experience together. There is no unit cohesion besides a shared desire to hurt people.

🚨WHOA. The El Paso Medical Examiner says it will rule the death of a 55-year-old Cuban man at ICE's "Camp East Montana" tent camp as a homicide. He was allegedly choked to death by a guard during a "struggle" after he refused to enter a housing unit without his medications.

By Douglas MacMillan
When U.S. Immigration and Customs Enforcement announced the Jan. 3 death of detainee Geraldo Lunas Campos at a Texas detention camp, the agency said “staff observed him in distress,” and it gave no cause of death.

An employee of El Paso County’s Office of the Medical Examiner told Lunas Campos’s daughter this week that, subject to results of a toxicology report, the office is likely to classify the death as a homicide, according to a recording of the conversation.

In the recording, which the daughter shared with The Washington Post, the employee said a doctor there “is listing the preliminary cause of death as asphyxia due to neck and chest compression,” which means Lunas Campos did not get enough oxygen because of pressure on his neck and chest. Pending the results of a toxicology report, the staffer said on the recording, “our doctor is believing that we’re going to be listing the manner of death as homicide.”In an interview with The Post, Santos Jesus Flores, a man who says he was detained in the segregation unit the day Lunas Campos died, said he saw at least five guards struggling with Lunas Campos after he refused to enter the segregation unit, complaining that he didn’t have his medications. Flores said he saw guards choking Lunas Campos and heard Lunas Campos repeatedly saying, “No puedo respirar” — Spanish for “I can’t breathe.” Medical staff tried to resuscitate him for an hour, after which they took his body away, Flores said.

“He said, ‘I cannot breathe, I cannot breathe.’ After that, we don’t hear his voice anymore and that’s it,” said Flores, who had contacted a family member of Lunas Campos, who in turn put him in touch with a Post reporter. The Post confirmed Flores was in Camp East Montana through ICE’s detainee locator.
