The man hurried up the Baltimore sidewalk with a camera in his hand as four black-clad hospital security guards walked toward him, then past him. One of them was pushing an empty wheelchair.

“So wait, y’all just going to leave this lady out here with no clothes on?” said Imamu Baraka, referring to a dazed woman wearing only a thin hospital gown and socks whom they had left alone at a bus stop Tuesday night in mid-30s temperatures. Her face appeared bloody, her eyes empty.

It was the latest incident of “patient dumping,” which has sparked outrage around the country — and one that, according to an expert, probably violated a 1986 federal law that mandates hospitals release those in their care into a safe environment.

“This kind of behavior is, I think, both illegal and I’m sure immoral,” said Arthur L. Caplan, founding head of the division of medical ethics at the New York University School of Medicine. “You don’t just throw someone out into the street who is impaired and may have injuries. You try to get them to the best place possible, and that’s not the bench in front of the hospital.”

The last time Joe Arpaio ran for office, he was trounced.

This was 2016, when Arpaio was looking to be reelected as sheriff of Maricopa County, Ariz., after having served in that position for six four-year terms. During that tenure, he gained national fame for what might charitably be described as his tough stance on immigration. Less charitably, his efforts have been described as abusive and racist. After he was subject to a variety of investigations and lawsuits, voters in the county apparently reached their fill of Arpaio and sent him packing.

This is not the last time he was in the news, of course. After being ordered to curtail his department’s racial-profiling practices and refusing to do so, Arpaio was convicted of contempt of court. That conviction led to a pardon from longtime ally President Trump in August, setting the stage for an unexpected announcement from Arpaio on Tuesday: He’s going to run for Senate.

People run for the U.S. Senate for a lot of reasons. It keeps them in the news, if they’re into that sort of thing, which Arpaio is. It allows them to raise money, which, in turn, allows them to tour the state on someone else’s dime. It also can lead them to serving in the Senate. Those are listed in the descending order of what Arpaio is likely to get out of his bid.

1. In Slovenia, I was a catalog model, which is what you call a model you order out of the catalog.

2. I’m the only First Lady to ever wear sunglasses to a hurricane.

5. I spent two years in a vault at Deutsche Bank when Donald defaulted on a loan.

7. I hope I inspire little girls everywhere to marry for money.

10. I once played Scrabble against Eric and the final score was 3 to 2.

17. My Secret Service code name is “That Poor, Poor Woman.”

18. I copied this list from Michelle Obama.

25. If I could tell my younger self just one thing it would be this: if you catch a leprechaun and he gives you a wish, be more specific.

THE PROBLEM WITH living your life under the spotlight is that the camera captures only the public eruption, not the months of silent anger. On Dec. 3, when the New England Patriots played the Buffalo Bills, Tom Brady walked to the sideline after throwing late and behind receiver Brandin Cooks on third down, ending a first-quarter drive. Brady was angrier and more irritable than usual, as has often been the case this season in the eyes of some Patriots players and staff. As he unsnapped his chinstrap, Brady passed offensive coordinator Josh McDaniels on the sideline.

"He was wide open," McDaniels said to Brady, referring to Cooks. Brady kept walking, and glaring at McDaniels, so the coach repeated: "We had him open."

Brady snapped, pivoting to McDaniels and yelling at him, "I got it!" Everyone within earshot, including head coach Bill Belichick, turned to watch as Brady screamed. He removed his helmet, and as a Patriots staffer held him back -- and with McDaniels' father and legendary high school coach in Ohio, Thom, in the stands behind the bench -- capped off the exchange by yelling, "F--- you!"

Video of the scene went viral, with many rationalizing it as a symptom of Brady's legendary competitiveness. Brady would later apologize to McDaniels, who dismissed the incident to reporters as "part of what makes him great." After all, many in the Patriots' building knew that Brady's explosion wasn't really about McDaniels. It wasn't about Cooks. And it wasn't about the Bills game. It was about the culmination of months of significant behind-the-scenes frustrations. For almost two decades, Belichick has managed to subvert the egos of his best player, his boss and himself for the good of the team, yielding historic results. This year, though, the dynamics have been different.

Dear Cecil: I recently adopted a black lab puppy. A neighbor who’s studying to be a vet and volunteers at a shelter gave me kudos, as it's known in shelters that black dogs are by far the least popular color and are hard to find homes for. Could racism really extend itself in a cross-species manner?

Cecil Replies: Well, your vet-student pal’s certainly right about one thing: it’s an accepted truth among animal-shelter staff that people just don’t want to take black dogs home. Articles and message-board commentary from shelter workers attest to this sad injustice; pounds across the country (and in some cases dedicated black-dog rescue groups) host special adoption events to try to get the poor creatures out the door.

Guess what, though? All the concern notwithstanding, this phenomenon — known as black dog syndrome — doesn’t seem to actually exist, at least as far as research has been able to demonstrate. And there’s a fair amount of research, BDS having long been a hot topic in the shelter world. Among the more recent findings:

A 2013 analysis of 1,200 dogs and puppies at two no-kill shelters in New York State saw no significant variation in length of availability for adoption (LOA, in the lingo) related to coat color. The study did find that LOA increased about a day per year of age for adult dogs, and that medium-sized dogs could expect to wait longest; adopters gravitated toward the smallest dogs and the biggest, and (understandably) to the puppies.
