“If at first you kinda suspect
get a warrant, what the heck?” (Well, it could have been Johnny Cochran)
Nice opinion in Commonwealth of Pennsylvania v. Gerald M. Dunnavant, a case that involved suppression of evidence obtained from a confidential informant wearing a silent video device in a suspect’s home when no warrant has been obtained:
The Commonwealth of Pennsylvania (“the Commonwealth”) appeals from the order entered on June 8, 2012 granting the suppression motion filed by Gerald M. Dunnavant (“the defendant”). On appeal, the Commonwealth argues that the suppression court erred by prohibiting for use at trial evidence obtained from a silent video camera worn by a confidential informant inside the defendant’s residence. After careful review of this issue of first impression, we affirm.
[...]
The video recording at issue was government behavior and, through the lens of a hidden, digital video camera, a warrantless search of the defendant’s residence. Thus, it is per se unreasonable. Blair, 575 A.2d at 596-597. The Commonwealth does not – and cannot – defend the video recording at issue with any of the specifically established and well-delineated exceptions to the warrant requirement. Even if the Commonwealth’s video recording inside the defendant’s living room was “inadvertent,” we hold that it was an unconstitutional invasion of the defendant’s expectation of privacy in his home. As such, the Commonwealth could not use the video recording against the defendant.


How did I miss this? I've got to re-visit my seminar finding tools...
If you missed the conference on Location Tracking and Biometrics at Yale yesterday, you missed an outstanding conference combining informative presentations and lively discussion and questions from the audience. But not to fear: it’s available for viewing (fast forward the first 40 minutes; it seems to start with Chris Soghoian’s overview of location tracking).
You can find the program here, with links to articles suggested by panelists. There were four panels:
Panel 1: The Fourth Amendment and tracking after U.S. v. Jones
Panel 2: Cellular phones and mobile privacy: Government requests to carriers
Panel 3: Cellular phones and mobile privacy: Direct government surveillance (Stingrays)
Panel 4: Nontrespassory tracking: Biometrics, license plate readers, and drones
There was just so much packed into the panel presentations and discussions that I can’t do it justice here, other than to just tell you: go watch and listen. You’ll thank me later, although the fourth panel may scare the bejesus out of you.
@EFFaustin provided yeoman service throughout the day, tweeting links to additional relevant articles and resources on the topics. I’ve compiled a list of some of the many tweets, which includes their suggestions as well as some resources tweeted by others:

Nothing on why the database is valued (or cost?) $100 million. That seems a bit high for something that so far has no data...
The road to Hell is paved with good intention$$?
Stephanie Simon of Reuters reports:
An education technology conference this week in Austin, Texas, will clang with bells and whistles as startups eagerly show off their latest wares.
But the most influential new product may be the least flashy: a $100 million database built to chart the academic paths of public school students from kindergarten through high school.
In operation just three months, the database already holds files on millions of children identified by name, address and sometimes social security number. Learning disabilities are documented, test scores recorded, attendance noted. In some cases, the database tracks student hobbies, career goals, attitudes toward school – even homework completion.
Local education officials retain legal control over their students’ information. But federal law allows them to share files in their portion of the database with private companies selling educational products and services.

Tell me that this isn’t a data security and privacy disaster waiting to happen. Go on, tell me. Potentially millions of Social Security numbers and disability information and the U.S. Education Department thinks this is just fine? The same federal agency that doesn’t require breaches be reported to them or to parents? I see….
[From the article:
The database is a joint project of the Bill & Melinda Gates Foundation, which provided most of the funding, the Carnegie Corporation of New York and school officials from several states. Amplify Education, a division of Rupert Murdoch's News Corp, built the infrastructure over the past 18 months. When it was ready, the Gates Foundation turned the database over to a newly created nonprofit, inBloom Inc, which will run it.
States and school districts can choose whether they want to input their student records into the system; the service is free for now, though inBloom officials say they will likely start to charge fees in 2015. So far, seven states - Colorado, Delaware, Georgia, Illinois, Kentucky, North Carolina, and Massachusetts - have committed to enter data from select school districts. Louisiana and New York will be entering nearly all student records statewide.


This article suggests we may be close to a “Heisenberg Compensator” – the last component before Star Trek “Transporters” become possible...
Schrödinger's Cat could be visible after all
Schrödinger's Cat could be (almost) as easy to observe as the internet's millions of LOLcats, with confirmation that there may be a way round Heisenberg's famous Uncertainty Principle after all.


An interesting application of Statistics (and a way to highlight new terms for students)
Five Ways to Create Word Clouds
This morning at the Massachusetts School Library Association's conference (a fun conference that I highly recommend) Pam Berger presented some good ideas for working with primary source documents and Web 2.0 tools. One of the ideas that she shared and others elaborated on was the idea of using word clouds to help students analyze documents. By copying the text of a document into a word cloud generator your students can quickly see the words that appear most frequently in that document. Here are five tools that you and your students can use to create word clouds.


Free is Good! Free stuff you actually want is better!
In case you weren’t aware there are a lot of eBooks available on the Internet that cost nothing. If you are willing to look, they are out there in a big way. However, finding them is not always as easy as you’d like it to be. They tend to be scattered around the web in different places. However, Bookresults makes it easy to find all kinds of free eBooks on the Internet.

The PDF file format has vastly become the default format for sharing digital documents online. Papers, eBooks, manuals, and a lot more can be found in the PDF file format on the Internet. If you need to find a digital document that is in the PDF file format and has been uploaded publicly, you should check out a website called Zyndle.
