Students form Human Chain for Survivors to protest U-M policy
The Human Chain for Survivors of Assault and their allies gather at the steps of Hatcher Wednesday afternoon.
Community members contest peer-to-peer cross examination practice chapter of the American Civil Liberties Union, hosted Wednesday’s event. Last year, the Sixth Circuit Court of Appeals ruled in the case of Doe v. Baum the University must allow cross-examination in sexual assault cases. The University petitioned for the Sixth Circuit Court to rehear the trial in October 2018, but was denied. The University’s interim policy implemented the crossexaminations and added a tenet that requires the question to be peer-to-peer. LSA sophomore Emma Sandberg is one of many

About 50 students protested Wednesday afternoon in the “Human Chain for Survivors” event on the Diag in front of Hatcher Library. The protest contested the University of Michigan’s interim Title IX policy requiring a peer-topeer cross-examination in all Title IX cases, including cases of sexual misconduct and assault. The policy has been highly contested since it was implemented in December 2018. Roe v. Rape as well as the University
students who has arg ued peer-to-peer questioning forces the perpetrator to question their victim, inciting trauma and anxiety in survivors. “When someone has been sexually assaulted, they feel a sense of powerlessness and that’s one of the big reasons why people report: to take back their power and stand up to their perpetrator,” Sandberg said. “When a university allows a perpetrator to cross-examine their victim, the university is in effect allowing that perpetrator to have power over the
victim again and I consider that to be cruel.” Sandberg founded the non-profit Roe vs. Rape over the summer and is currently executive director of the organization. “The group helps survivors through activism and attempts to prevent sexual assault through education,” Sandberg said. Protestors linked together with a rope and the number of participants grew from ten to 50. Some protesters held signs in addition to the chants. See CHAIN, Page 3
Vulnerabilities in virtual assistants such as Amazon Alexa or Google Assistant may allow laser beams to imitate audio commands and hack into these devices, researchers at the University of Michigan and the University of ElectroCommunications in Tokyo have found. Using a laser beam with just five milliwatts of power for the virtual assistants and 60 milliwatts for smartphones and tablets, the researchers discovered the lasers can activate and hack different virtual assistants just by aiming light at different intensities into the microphones, calling the tactic “light commands.” The changing intensities of light act as sound waves that cause the microphone to react as if it is hearing sound. Engineering graduate student Benjamin Cyr, a member of the light commands research team, said light commands can be dangerous as they can grant individuals access to important information from far distances. “With these devices, you

City commission seeks to join movement to reduce fatalities from mobility, transportation
Chris Calabrese, vice president for policy at the Center for Democracy and Technology, was hosted by the Science, Technology and Public Policy program, Center for Ethics, Society and Computing and InSPIRE at the Ford School of Public Policy on Tuesday. About 50 students and community members attended the lecture entitled, “Show Your Face?

Aaron Valdez, communications coordinator at Sweetland Writing Center, has a daily eight-mile commute round trip between Ypsilanti and the University of Michigan campus. As a biker, Valdez said Fuller Avenue is a problem area for commuter safety. “It’s one of those places where I always have a problem every single day with almost being dead or watching someone almost being dead,” Valdez said. “I’m looking for some sort of solution to prevent these daily near-misses that happen.” On Wednesday night, Valdez attended Ann Arbor’s Moving Together Towards Vision Zero open house at Larcom City Hall. Joining a national movement to reduce fatalities resulting from mobility and transportation in cities, Ann Arbor is headed to become a Vision Zero City. The city hosted the open house, which attracted about 50 community members like Valdez, to obtain feedback on bike lanes and transportation problem areas. See TRANSPORTATION, Page 3

The Pros and Cons of Facial Recognition Technologies for Our Civil Liberties,” where Calabrese explained the social and ethical context of facial recognition technology. “As we incorporate more and more technology into our lives, we need to think about the impact of that technology and what we want to do with it,” Calabrese said. “Face recognition is a really good example. It is powerful, it is useful and it is often dangerous. Like many technologies, it is a
technology that can do so many things. It can find a wanted fugitive from surveillance footage. It can identify everybody at a protest rally.” Calabrese explained the basic framework of the technology. “It is a sort of measurement of people’s faces,” Calabrese said. “It is turning them into a discrete number that can be stored in databases and used to compare against other photos to see if I get that same measurement and see if I’ve identified that person.”
In the last five years, the National Institute of Standards and Technology has confirmed massive gains in the accuracy of facial recognition technology. This has been due to a variety of factors, including more powerful computers, greater data storage and more advanced artificial intelligence. Calabrese also commented on the privacy repercussions of facial recognition advancements. See TECHNOLOGY PAGE 2
have them in a secure location within a home where a passerby can’t talk and have it activate,” Cyr said. “But light, if it’s focused, will travel through windows and from long distances.” Cyr said some of the tests the team completed were able to activate the devices with a laser beam from a distance of more than 100 meters. The team tested 17 different virtual assistant devices using a tripod, telescope and telephoto lens. Videos on the research project’s website show the team successfully injecting different commands from varying distances into the Google Home device to open a garage door and to say what time it is, once from the top of the North Campus bell tower to an office in the Bob and Betty Beyster building. The researchers successfully hacked into virtual assistant devices using equipment, some bought from Amazon, for a total under $500. Though they had previously not heard of light commands being used to hack into virtual assistants, Cyr said the technique would be very easy for an individual to use. See HACKING, Page 3

TEDxUofM panel talks sustainable food needs Industry professionals, students reflect on how decisions can impact environement BECCA HIRSH For The Daily
About 50 students attended a TEDxUofM Salon event entitled “Eating Your Way to a More Sustainable Future” Wednesday evening in North Quad. The event featured a panel of five sustainable food industry experts from the University of Michigan and the Ann Arbor community. The event started by watching a TED Talk by Bruce Friedrich, co-founder and executive director of The Good Food Institute. In the video, Friedrich discussed how to create alternatives to the meat industry that cost the same or cheaper and taste the same or better than conventional meat. Kathy Sample, owner and founder of Argus Farm Stop, a farmers market in Ann Arbor, emphasized her relationship with food and dedication to sustainability in her introduction. “I feel like the community around food is what makes families strong and what makes groups of people care about each other and spend time together doing something that’s meaningful,” Sample said.
