While early reports Tuesday quoted police saying that 31 people had been arrested last night, NBC News says it has more recent data showing 78 arrests.
It's hardly like World War II or anything, but Americans are increasingly finding ways to go without orange juice. Consumption has fallen to the lowest level since 2002 according to fresh numbers from Nielsen -- we have more on why the breakfast staple is becoming less popular. And as families pack their 18-year-olds for college, they're confronted by the tuition costs. Then there's the cost of text books: one estimate puts the average at $600 for books and materials; another estimate runs twice that. Some students save money by renting or buying textbooks. But others don't get the books at all, which can cause big headaches for the instructors leading their classes. As you've been hearing, two people were shot last night and more than 30 arrested in more confrontations in Ferguson, Missouri. Among the many issues that will be examined is the flow of post-9-11 federal money that critics say has lead to the militarization of American police forces. And there are calls now for police officers to wear video cameras on the job. But that solution may only lead to more questions.
On the last day of a pediatric dentistry course offered this summer at the University of Minnesota, adjunct assistant professor Jen Post asked her class a pointed question.
"For the purposes of planning for next year, I'm just wondering how many of you bought the book for this course," she asked. "Anyone?"
Not one aspiring dental hygienist raised a hand.
The $85 textbook was, technically speaking, optional. But Post says even when it was required in years past, few students bought it. They also didn't even try to rent or borrow it.
"Then they didn't know answers on exams. They didn't know where it was coming from," says Post.
Faculty at several other schools report similar problems. In a survey conducted last fall by the National Association of College Stores, nearly a third of students polled said they didn't buy or rent at least one item required for a class, often a textbook. And an equal share of students waited until after the start of school to buy anything.
"They want to make sure that whatever's required of them to purchase or rent or borrow from someone else, that they're going to be used," says Richard Hershman, vice president of government relations for the trade group.
Niki Marinelli, a senior in the dental hygiene program at the University of Minnesota, says she often just relies on study guides or will borrow a textbook from a friend to avoid buying books.
"Sometimes I see how I did on the first test and go from there. I see if I feel a book would've been helpful if I didn't do so well," she says. "Most of the time I'm okay. I'll go in if I have any questions."
Marinelli says loans cover the $10,000 she pays each semester in out-of-state tuition. But book costs come out of her own pocket. And she already works two jobs.
Rick Hess, director of education policy studies at the American Enterprise Institute, says professors need to be sensitive to textbook affordability. But he says it's shortsighted of students to spend thousands of dollars on tuition and then skimp on books.
"It's a case of students essentially seeming to think they're paying for the credential for the degree but they're not all that concerned about the learning that goes along with it," he says.
Jen Post is concerned about it. Post now filters the textbook content down to 50-minute powerpoint presentations, which are the basis of lectures and exams. It's the best way to ensure students get exposed to the information in the book. Post says if she didn't do this, her students would turn instead to Google and YouTube for answers to their homework assignments. And those answers are often wrong.
"They're just thinking everything's at their fingerstips," she says, "when it might be in the book."
Civil unrest in Ferguson has put a spotlight on the issue of excessive force by the police. One possible answer: have officers wear cameras while on the job.
With video cameras and cloud storage getting cheaper by the day, it would seem outfitting police with cameras should be easier than ever, right?
“What happens to the data after the fact? How long is it stored for? What’s done with the data after an investigation has concluded?” Lynch said.
Another issue: If the video is being used as evidence, how do you secure it from hackers and establish a chain of custody?
Putting those systems in place takes technical expertise and money, something many police departments are short on, said Jen King, with UC Berkeley’s School of Information.
King says that because of the sensitive nature of the videos, public agencies can’t always use off-the-shelf products.
“It’s not like they can just buy cloud space,” she said.
Some jurisdictions don’t allow public agencies to store information in the cloud and so they have to maintain their own servers - which is another cost.
