In the wake of man bringing live bombs, zip gun to Sac elementary school, major leap announced in campus protection tech

Authorities are being tight-lipped about what might have motivated Gustavo Aguilar, the 57-year-old man arrested last week for allegedly bringing two improvised, working bombs and a loaded homemade gun to Ethel Baker Elementary School in South Sacramento. Meanwhile, on the global front, a Canadian company confirmed that it’s racing ahead with a novel technology designed to stop such threats to school campuses.   

The investigation into Aguilar began shortly after 8 a.m. on March 2, after a program manager working at Ethel Baker noticed two suspicious devices resting on a sidewalk near one of the entrances.

Children were due to arrive at the school that morning. Even with COVID-19 restrictions, Ethel Baker has been one of the Sacramento City Unified School District’s learning hubs, a place where community groups partner with school staff to offer distance-learning support to students. This generally involves providing computer access to roughly 40 kids at a time, with an adult supervising as they log-in for classes.  

According to SCUSD Chief Communications Officer Tara Gallegos, the students hadn’t arrived on campus when the first menacing devices were uncovered.

“Our principal was able to get ahold of the students quickly, and made sure they knew to stay home,” Gallegos told SN&R. “Because this happened so early, most of the staff hadn’t arrived yet, either.”

Sacramento Sheriff’s personnel converged on Laurine Way. An Explosive Ordnance Disposal Team soon approached the devices. Sheriff’s Sergeant Rod Grassmann said that one was a 2.5-inch diameter steel pipe, sealed at both ends, with an improvised fuse on it. It was packed with metal shrapnel, clay putty, firecrackers and gasoline.

The other device was a “zip gun” made from a steel pipe. It had a spring-loaded cap that could fire a 12-gauge shotgun round. The zip gun was loaded.

No one was harmed as the Sheriff’s team neutralized both devices.

Another live pipe bomb was found on the campus on March 19.

Five days later, Sheriff’s detectives arrested Aguilar.  He was booked into the Sacramento County Main Jail on CONTINUE READING: In the wake of man bringing live bombs, zip gun to Sac elementary school, major leap announced in campus protection tech • Sacramento News & Review

Big Brother Knows What's In Your Heart

Well, this is creepy.

Before the pandemic, Ka Tim Chu, teacher and vice principal of Hong Kong's True Light College, looked at his students' faces to gauge how they were responding to classwork. Now, with most of his lessons online, technology is helping Chu to read the room. An AI-powered learning platform monitors his students' emotions as they study at home.

The software is called 4 Little Trees, and the CNN article only scratches the surface of how creepy it is. So let's work our way down through the levels of creepiness.

4 Little Trees is a product of Find Solution AI, a company founded in 2016. This product appears to be the heart and soul of their company. Though their "about us" mission statement is "FSAI consistent vision is to solve the difficulties that the society has been encountered with technology." They might want to look at their placement of "with technology" in that sentence. Anyway, on to 4 Little Trees.

It uses the computer webcam to track the movement of muscles on the student face to "assess emotions." With magical AI, which means it's a good time for everyone to remember that AI is some version of a pattern-seeking algorithm. AI doesn't grok emotions any more than it actually thinks-- in this case it compares the points it spots on the student's face and compares it to a library of samples. And as with all AI libraries of samples, this one has issues--mainly, racial ones. 4 Little Trees has been "trained" with a library of Chinese faces. The company's founder, Viola Lam, is aware "that more ethnically-mixed communities could be a bigger challenge for the software." 

But aren't emotions complicated? The sample image shows the software gets to choose from varying amounts of anger, disgust, fear, happiness, sadness, surprise and neutral. The company calls these CONTINUE READING: CURMUDGUCATION: Big Brother Knows What's In Your Heart

FL: Big Brother Is Watching Your Child

Eyebrows shot up around the country this week as the Tampa Bay Times reported on how the Pasco County Sheriff's Office keeps a secret list of "at-risk" kids who could “fall into a life of crime." Creating the list involves the office collecting and factoring a whole bunch of different you-probably-thought-they-were-confidential records, including records from the school district and from the state's Department of Children and Families. 

"We have an agreement with the Sheriff's Office," the superintendent said in an interview with the Times. "The agreement requires them to use (the data) for official law enforcement purposes. I have to assume that's exactly what they are using it for."

Low grades? Absenteeism? Violence in the home? You may well be flagged as a possible future criminal. The Sheriff's Office has a whole manual. And a list, with 420 names on it. And none of the families connected to the names knows a thing about it. This is not a targeted search, where someone is concerned about Pat McStudent; this is a blanket sweep of the entire list of records from the various institutions.

Mark Lieberman at EdWeek did some checking to see if this practice is illegal (if you're old enough, you may remember when FERPA protected students from this kind of thing). The answer seems to be CONTINUE READING: CURMUDGUCATION: FL: Big Brother Is Watching Your Child
