New York City Mayor Bill de Blasio today announced police will no longer require people to wear masks in public, unless the absence of a mask presents a "serious danger."

Medical rationing is not something Americans are accustomed to, but COVID-19 may soon change that.

The specter of rationing is most imminent in New York City, where the virus is spreading rapidly and overwhelming hospitals with patients.

According to New York Gov. Andrew Cuomo, the state has 2,200 ventilators in its state stockpile. Current COVID-19 case projections suggest the state may not have enough of the machines, which help critically ill people breathe, as soon as next week.

As COVID-19 spreads, public health officials are telling people to stay home if they feel sick. But in jails and prisons, that's not an option.

Robert Greifinger is a physician who spent 25 years working on health care issues inside the nation's prisons and jails, and he says the "social distancing" advice we're all hearing right now isn't so simple behind bars.

"There are crowding issues, ventilation issues, security issues where people have to be checked and monitored fairly frequently," Greifinger says. "So it's really hard to do."

The Trump administration has revived the debate over "end-to-end encryption" — systems so secure that the tech companies themselves aren't able to read the messages, even when police present them with a warrant.

"It is hard to overstate how perilous this is," U.S. Attorney General William Barr said in a speech last fall. "By enabling dangerous criminals to cloak their communications and activities behind an essentially impenetrable digital shield, the deployment of warrant-proof encryption is already imposing huge costs on society."

Cybercrime is booming, and victims are often at a loss about where to get help.

In theory, Americans should report the crimes to the FBI, via its Internet Crime Complaint Center. In practice, the feds get hundreds of thousands of complaints a year, and have to focus on the biggest cases.

But the other option, calling the police, can seem even less promising.

Over the last generation, gun rights have expanded in America, especially the right to carry firearms, both concealed and in the open. The big exception to this expanding gun culture has been New York City.

The secret to comedy, according to the old joke, is timing. The same is true of cybercrime.

Mark learned this the hard way in 2017. He runs a real estate company in Seattle and asked us not to include his last name because of the possible repercussions for his business.

"The idea that someone was effectively able to dupe you ... is embarrassing," he says. "We're still kind of scratching our head over how it happened."

Scammers are always looking for more effective words. Most Americans have learned to be on their guard, and they're likely to suspect an overly aggressive phishing phone call from a fake credit card customer service agent speaking accented English.

Gregg Bennett is an entrepreneur in Bellevue, Wash., and he knows a bit about tech. So when his smart phone started acting funny one day last April, he got a bad feeling.

"I was having trouble getting into my email account. And all of a sudden my phone went dead," he says. "I look at my phone and there's no signal. And I go, 'Oh no, something's happened here.'"
