Since the Ferguson, Mo., shooting, there have been renewed calls for police departments to hire more minority officers, but it turns out it's not that simple.

Police in the U.S. are more diverse than they were a generation ago. In the 1980s, 1 in 6 officers belonged to an ethnic or racial minority. Now it's about 1 in 4. The challenge these days is finding enough recruits to keep that trend going.

When Americans sit down to their Thanksgiving meal, most tables will feature traditional fare: turkey, mashed potatoes, cranberries. But should you be looking for a different kind of holiday meal, head for rural Alaska.

That's where Nellie Gamechuck lives, in a village squeezed between tundra and a bend in the river in the southwest part of the state. Ask her what's for dinner on Thanksgiving, and she opens up the deep freeze. "Walrus meat, moose meat," she says. Digging down through the layers, she reaches the dessert level: salmonberries.

It was already known that the FBI uses spyware to investigate people — that was clear in federal documents obtained by the Electronic Frontier Foundation. What hasn't been fully appreciated until now was the lengths to which the FBI will go to infect a target's computer.

"Presumably, your typical Nigerian scam email offering $10 million dollars isn't going to work," says Christopher Soghoian of the ACLU.

The protests that followed the shooting death this month of Michael Brown in Ferguson, Mo., have rekindled long-standing complaints about racist policing, especially in the St Louis area.

Many male African-American residents there say police scrutinize them unfairly. "Every time you see a cop, it's like, 'OK, am I going to get messed with?' " says Anthony Ross. "You feel that every single time you get behind your car. Every time."

Now, police officers in and around St. Louis are becoming more vocal about defending themselves against the charges of bias.

Body-worn video cameras are quickly becoming standard-issue for American police, especially at departments in the process of reform. And in New Orleans, the troubled police department is now requiring almost all officers to wear the cameras.

The city's police department has a dark history of corruption, racism and brutality. The low point may have been the Danziger Bridge episode, after Hurricane Katrina, when police shot unarmed people, then covered up the crime.

These days, the department is trying to rebuild the public's trust — which is where the body cameras come in.

Montana resident Markus Kaarma pleaded not guilty Wednesday to charges of murdering a German exchange student last month. Kaarma shot the 17-year-old while the student was trespassing in his garage. The case has attracted international scrutiny to the contentious debate over how far Americans may go when defending their homes.

The people who design marketing apps are celebrating a change in the way iBeacon works on iPhones. That's the Bluetooth-based system that lets a store track a customer's movements, and capitalize on them. For instance, if iBeacon detects you lingering in the shoe department, it might send you a digital coupon for socks.

New software and gizmos are revolutionizing police work, with social media scanners, facial recognition and other high tech items. As it turns out, though, the single most valuable new police tool is your smartphone.

Contractors working for the state of Washington are planning a high-stakes operation to rescue Bertha — the world's largest tunneling machine.

Bertha is supposed to be boring a 2-mile highway tunnel under downtown Seattle, but it got stuck in December.

Bertha is on Seattle's waterfront, between South Main and South Jackson streets, about 60 feet straight down. At first, they thought the machine was being stymied by a big glacial rock. Then attention focused on the chewed-up remains of a metal pipe. But now it seems Bertha's ailment is mechanical.

Social monitoring started in the world of marketing, allowing companies to track what people were saying about their brands. But now, with software that allows users to scan huge volumes of public postings on social media, police are starting to embrace it as well.

Many police departments in Britain use a product sold by CrowdControlHQ. CEO James Leavesley calls it a "social media risk media and monitoring" company, meant primarily as a means of staying in touch with the public. But Leavesley says it's also a way to detect trouble.

Police are like the rest of us; they suffer from information overload. The data pour in from 21st century sources ranging from license plate readers to Twitter. But as the information comes in, it hits an old-fashioned bottleneck: human beings.

When I heard late Thursday that Attorney General Eric Holder had come out in favor of bank accounts for state-sanctioned pot businesses, I assumed the industry would react with cheers. After all, they've long complained about being black-balled by banks, which are justifiably afraid of violating federal laws against handling drug money.

But when I started calling around today, the reactions ranged from "That's nice" to "Meh."

Ever wonder what happened with Bertha — the world's biggest tunneling machine, stuck under Seattle? We last checked in on the story right before Christmas, when engineers were preparing to send down inspection teams to identify the blockage. People (OK, the media) were having a grand time, floating ridiculous guesses about what the mysterious object might be. An old ship? Dinosaur bones? Bigfoot?

One month later, there's still no clear answer. Certainly nothing headline-grabbing.

If you think the recent liberalization of marijuana laws around the country is only about smoking leaves and buds, think again. For users younger than 25, "hash oil" is where it's really at. This concentrated resin of marijuana is creating new public safety headaches — even in places where it's legal.

There have always been forms of the substance, but the resins available today are much stronger than in years past. That's due in part to the expertise developed by medical marijuana producers, who have learned how to make more potent versions of the oil.
