Researchers in the lab of UC Santa Barbara professor Yasamin Mostofi have enabled, for the first time, determining whether the person behind a wall is the same individual who appears in given video footage, using only a pair of WiFi transceivers outside.

This novel video-WiFi cross-modal gait-based person identification system, which they refer to as XModal-ID (pronounced Cross-Modal-ID), could have a variety of applications, from surveillance and security to smart homes. For instance, consider a scenario in which law enforcement has a of a robbery. They suspect that the robber is hiding inside a house. Can a pair of WiFi transceivers outside the house determine if the person inside the house is the same as the one in the robbery video? Questions such as this have motivated this new technology.

“Our proposed approach makes it possible to determine if the person behind the wall is the same as the one in video footage, using only a pair of off-the-shelf WiFi transceivers outside,” said Mostofi. “This approach utilizes only received power measurements of a WiFi link. It does not need any prior WiFi or video training data of the person to be identified. It also does not need any knowledge of the operation area.”

Under his plan, “Justice and Safety for All,” Bernie Sanders wants to ban facial recognition software for policing. As a supporter of Sanders, I’m going to have to respectfully disagree. Here’s why…

Last Sunday, presidential-hopeful Bernie Sanders released on his website what is arguably one of the most extensive plans for law enforcement oversight and criminal justice overhaul that the United States has ever seen. As a progressive, myself, and supporter of Sanders during his primary run, I fully endorse everything that’s been laid out in this plan— that is, except for one minor policy.

The plan, titled “Justice and Safety for All,” calls to “Ban the use of facial recognition software for policing.” It also calls for a “moratorium on the use of the algorithmic risk assessment tools in the criminal justice system until an audit is completed,” whereby the audit would “ensure these tools do not have any implicit biases that lead to unjust or excessive sentences.”

I’m perfectly fine with the policy on algorithmic risk assessment tools being used by our criminal justice system. It’s not a total ban; it simply serves as a temporary safety measure until it’s been proven that these algorithms won’t carry with them any unjust biases. But when it comes to Sanders’ policy on banning facial recognition software for policing, I simply cannot get behind it.

A water bottle recovered from a construction site where Tim DeSalvo – whose uncle Albert DeSalvo had confessed to being the internationally notorious Boston Strangler – gave police the DNA evidence they needed to bring closure to a case that has been a mystery for nearly 50 years, murders for which no one has ever been charged.

“This is really a story of relentlessness,’’ Boston Police Commissioner Ed Davis explained today as Massachusetts top law enforcement officials revealed that DNA preserved from the body of the Boston Strangler’s last victim—raped and murdered in 1964—can now be linked with ”99.9 percent certainty” to the late Albert DeSalvo.

”This is good evidence. This is strong evidence. This is reliable evidence,’’ Suffolk County District Attorney Dan Conley said of the new DNA result. ”But there can be no doubt.”

This article appears in Weekly Health Page July 31.

Researchers found that more than four out of five Ohio women who had been physically abused by their partners had suffered a head injury. A study that found domestic violence survivors had sustained staggering rates of head trauma and violent choking incidents suggests that many are left with ongoing health problems from “invisible injuries” to the brain.

But the effects of such injuries often go unrecognized by advocates, health care providers, law enforcement — even the victims themselves, researchers said.

“Over the past 50 years [America has] gone from institutionalizing people with mental illnesses, often in subhuman conditions, [in state mental health hospitals] to incarcerating them at unprecedented and appalling rates—putting recovery out of reach for millions of Americans […] On any given day, between 300,000 and 400,000 people with mental illnesses are incarcerated in jails and prisons across the United States, and more than 500,000 people with mental illnesses are under correctional control in the community.” [1] Mental Health America (MHA) supports effective, accessible mental health treatment for all people who need it who are confined in adult or juvenile correctional facilities or under correctional control. People with mental health and substance use conditions also need an effective classification system to protect vulnerable prisoners and preserve their human rights. [2] Notwithstanding their loss of their liberty, prisoners with mental health and substance use conditions retain all other rights, and these must be zealously defended.

Background

In the past decade, America has been locking up increasing numbers of individuals with mental health conditions. [3] MHA is both concerned by and opposed to the increasing use of criminal sanctions and incarceration, replacing the state mental hospitals with much more drastic curtailment of personal liberty and preclusion of community integration and community-based treatment. [4] Prisoners with mental health conditions are especially vulnerable to the difficult and sometimes deplorable conditions that prevail in jails, prisons, and other correctional facilities. Overcrowding often contributes to inadequacy of mental health services and to ineffective classification and separation of prisoner classes. It can both increase vulnerability and exacerbate mental illnesses. For these and other reasons, MHA supports maximum reasonable diversion. [5].

If 150,000 volt stun guns aren’t enough to deter criminals, law enforcement might want to give Rob Flickenger a buzz.

The IT expert, who also has a bit of a reputation as a DIY mad-scientist, has a shocking new invention: a real-life lightning gun. Built over a period of at least 10 months, the zapper is the end result of combining the aim-and-shoot functionality of an aluminum-encased Nerf gun with the electrical power supplied by an 18V drill battery.

The gun, which some of you might have guessed, is essentially a weaponized version of a Spark Gap Tesla Coil. To generate a high-voltage discharge, Flickenger designed a system that channeled the power drill’s 18V of power into a ZVS driver circuit, which in turn drives a flyback transformer, thereby raising the voltage to about 20,000V. All of this is admitted pretty technical, so if you want a detailed explanation of how it works, check out his site Hackerfriendly.com, where he goes through the finer points of the technology.

Cell-site simulators, also known as Stingrays or IMSI catchers, are devices that masquerade as legitimate cell-phone towers, tricking phones within a certain radius into connecting to the device rather than a tower.

Cell-site simulators operate by conducting a general search of all cell phones within the device’s radius, in violation of basic constitutional protections.


Law enforcement use cell-site simulators to pinpoint the location of phones with greater accuracy than phone companies. Cell-site simulators can also log IMSI numbers (unique identifying numbers) of all of the mobile devices within a given area. Some cell-site simulators may have advanced features allowing law enforcement to intercept communications or even alter the content of communications.

The Navy sent its expeditionary fast transport ship USNS Spearhead to sea to experiment with a number of cutting-edge technologies last week, including MartinUAV’s novel V-Bat drone. V-Bat is capable of infrastructure-independent vertical takeoff and landings while also retaining the high efficiency of a fixed-wing aircraft for long-endurance missions. Seeing as it can be launched and recovered in a nine square meter area and even in dense urban terrain, as well as on the tight decks of ships, the drone could have a lot of applications in the military, law enforcement/first responder, industrial, and environmental monitoring sectors.

In a milestone for forensic criminal investigators, a convicted killer received two life sentences on Wednesday for a 1987 double slaying after becoming the first person arrested through genetic genealogy to be found guilty at trial.

“The conviction and sentencing of William Earl Talbott II marks a new era for the use genetic genealogy for identifying violent criminals since it has now been tested and tried in a court of law,” geneology expert CeCe Moore told ABC News.

William Earl Talbott II was arrested in May 2018 and charged with aggravated murder for the Washington state cold case killings of 20-year-old Jay Cook and 18-year-old Tanya Van Cuylenborg, authorities said. A jury found Talbott guilty last month.
