in pakistan, people gathered for a vigil, and the foreign minister confirmed that six pakistanis were among the dead, includina father and son. the suspect in the terror attack appeared in court saturday morning, where he was charged with murder and ordered to return april 5. the judge ordered the man's face blurred in video released to the media. before he launched his aacks, the gunman emailed a long manifesto to media outlets and government officials and used multiple social media platforms to distribute his racist and hate-filled messages. joining me now for a discussion about the media's role and responsibility are: charlie warzel, opinion writer-at-large for the "n york times"; and from boston, joan donovan, director of the technology and social change research project at harvard university's shorstein center on media, ielitics and public policy. charlie warzel chaarzel joan donovan technology and social change research project charlie, let me start with you. be streamed live,e or torture unfortunately, in our modern what waferent about this is diera.

in my mind, t premeditated nature and sort of rather meticulous planning that wnt into setting up, you know, a couple of twitter accountses that were crated earlier this month to show pictures of some of the weapons that the shooter used, some of the body armor, to set up links to this manifesto, to a couplef other documents. so there's this, you know, this idea of not only is this attgoak g to be live streamed, but there's going to be a trail for people to follow. the things inside that are goinn to be sort oneered to sew discord to start fights, to provoke, and to get the media, obviously-- as we are all doing-- to pick up on this. >> sreenivasan: joan, whkin is kind of engineering, asnd charlie mentioned, how do we stop the spread of this?yo called yesterday for-- the phrase i think is strategic silence. how do we do that? >> yeah, so my research really centers on the ways in which the

press has interacted with white supremacists since the 1920s. that's one of the thii research. i think journalists' responsibility has been heightened by the fact which shifts the burden actually for strategic amplification to platform companies. and although the platform companies have been saying fo years, we're trying, we're trying, in moments like this we ed results. >> sreenivasan: charlie, how do we-- the idea that we are c actualtributing to amplifying this signal. so how do we report on it-- which is sti-- importaut in a way that doesn't fall into ing trap that joan is lay ou >> i think it's a massive challenge. but i think, in my own reporting, something that i've tried to do is to talk mu more about the mechanics and the idea of manipulation, how these platforms are being leveraged, demonstrating, walking readers,

listeners,iewers through how something like this takes place, how it was engined to get to you fall into those traps and not focusing on the actual message of hate and violence is something that not only takes away the power the an ext like, that but also lays sort of bare the philosophy and hel you sort of guard against it in further-- becreause theill be more of these types of things. >> sreenivasan: joan donovan, i've also seen some critique last night saying, hey, you know, what? if this was a muslim shooter, and if he or she had t out a manifesto like this, the f.b.i. and everyone else would go through every single paragraph, look at every possible inspiration, whether it's a video game, it's a person, it's a politician, and lay the blame squarely at their feet. are we giving is instance some sort of a double standard? >> i don't think so. i've seen a lot of people trying to hold the language used the trump administration accountable

for the way in which pople are starting to understandia islamoph anti-semitism, as well as, you know, this word "invasion" has come up more than a few times. and, you know,e're dealing here with this manifesto in a very, like, tired white nationalist conspiracy theory nabout white geocide and the depletion of the white race. this-- this exists online everywhere for all to see. like, it's on every platform. it just hasn't been amplied to this degree because of the violence that was perpetrated in the name of thedeology. and the point about law enforcement or the f.b.i yeah, we do know that the u.s. government is looking lesand less at, you know, white nationalist groups in the u.s., wed i think that's a really big problem. re watching this burgeoning

movement that-- all movements have ebbs and flows. hen movements are in moments of success, there'sot of fracture. the coalition tends to break apart. and so, an event like this could actually galnize or reanimate a movement. and so i'm very happy to see that journalists are not calling upheir, you kw, any neo-nazi that they can find and giving them a new place to air their ideology. i think is also difficult is, you know, i really want to talk about strategic silence in relationship to white supremacist ideology. it's not always the case that we need to treat every single badg that happens online as the same thing. i think for white supremacists and white nationalists or white identity extremists, we need to have a very concerted strategy

that focuses in on the actors and the influencers. >> sreenivasan: joan donovan from harvard university. and charlie warzel withhe "new york times." thank you. >> thanks. >> sreenivasan: french investigators today began studying the cockpit vce recorder from the ethiopian airlines jet that crashed last sunday, killing all 157 people on board. france's air accident investigation agency released a orphoto showing the data rr intact but damaged, and said it is also continuing to examine the flight recorders. boeing's 737ax 8 planes remain grounded as investigators look for similarities to a lionir crash in indonesia last october that killed all 189 people on board. ethiopian airlines is planning to hold a memorial service for victims of last sunday's crashow tomon addis ababa. to learn how you can help in tht afteof friday's terrorist attack in new zealand, visit www.pbs.org/newshour. >> sreenivasan: for people wit disabilities, one of the most difficult jobs is actually getting a job.ng

in fact, accoro the u.s. labor department, only around 30% of people with disabilities are currently employed. and one barrier to looking for and keeping employment might not be so obvious: clothing. uniforms and office attire often aren't designed with disabilities in mind. but as newshour weekend's megan thompson reported this past fall, one ogram at the parsons school of design here in new york city is trying to change l that, training fashion designers to think more inclusively and pushing the industry to change. >> reporter: every morning, christina mallon picks out an outfit for her job at a marketing firm in new york. mallon loves fashion and wants to look her st, but deciding what to wear isn't the biggest issue. >> for the last eight years, slowly, both my arms and shoulders became paralyzed. they don't exactly know what i have. they think it's motor- disease, most similar to a.l.s. >> reporter: when mallon's muscles began to atrophy, her old clothes noonger fit or became too difficult for her to put on by herself. >> fashion is a way toxpress

your soul and your personality. so, and me being a fashionista since i was a child, it was ve difficult that i couldn't wear my remaining clothing because i felt like a part of my identity was dying. >> reporter: mallon went online and looked at othes designed for people with a disability, but what she found was disappointing. >> i colors that i would never wear. a lot of fleeces, nothing fitted, a lot of velcro. and that just wasn't me. it just made me really upset that i didn't even want to go out of the house. >> reporter: then, last year, mallon found someone who could help. >> our mission has always been to make style accessible. >> reporter: grace jun leads open style lab, a non-profit based at the parsons school of design in new york, one of the nation's premier fashion institutes. the lab runs a summer program that trains participants to create clothing that ise inclusd accessible. >> one out of five people identify having a disability ine the united s which means

d ere's a whole untapped market that's marginalid haven't en addressed. >> reporter: christina mallon's team made her a stylish coat, free of charge. >> and being able to put a coat on by myself was the dnce between me having enough confidence to go to work. and things like that hpae such a big that people don't understand. >> welco, welcome. >> reporter: newshour weekend followed open style lab's ten-me week sprogram from day one, to see how it works. >> lack of accessible clothing is a barrier to greaterpe inence. >> reporter: the participants were divided into teams. each has a desner and an engineer. >> i want you to hold it all the way in your palm. >> reporter: plus, there's an occupational or physical therapist. they worked with residents ofth riverside premier rehabilitation and healing center in manhattan. the first task? getting to know the residents' needs. >> sweater-type material is hard e put on because it's bulky. >> reporter: roxssette had a stroke and is working to regain the use of her right arm.

>> i'd like to use it again, and i don't use it at all. >> reporter: being unable to dress one's self is a big part of the lost independence that disability can cause. roxie tells her team she gets frustrated waiting for an aide every morning to come help her get dressed. >> and so, we're going to find a piece of clothing that she'sto goine able to get on independently, without assistance from her caregiver.m >> i get t, the pants up. >> reporter: ada stewart has severe rheumatoid arthritis. her team learned that it took her a full eight minutes to pull on a pair of sweatpa they set about engineering something easier for her to pint pout. shother resident has parkinson's disease. gets cold easily and has pain and weakness in her arms. > wanda loves music and singing, and she told her team her favorite memory wa aonce performiamateur night at the apollo. so, they decided to create a rock & roll leather jacket that she can over her head, which is less painful than pulling on from behind.

the teams must rethink typical garment construction, everything from design to materials. roxie's team itrying to figure out how to make a wrap dress that she can put on using only one arm. >> hand through the sleeve. >> hand through the sleeve. >> reporter: roxie typically required a lot of help getting dressed, but she managed to pul on a prototypeis dress almost completely by herself. for people with paralysis or limited dexterity, fasteners like buttons or zippers can be difficult. roxie's team tried magnets, but it tned out they didn't work that well, either. >> it was sticking to the wheelchair, and it made it difficult to maneuver the garment. and so, we hadtho eliminate . >> blue is for your arms, and pink is for your head. >> reporter: the teams visited se clients regularly to out the garments and make sure they fit. >> how does that feel? >> i don't know. like, it's still tight. >> reporter: as the summer went on, ada stewart's outfit slowly took shape. the team tested different types of pleats for the pants lld devised a system that will gather up the pants for

her, making it easier to get her feet in. >> nice and warm. look at th pockets! >> reporter: ada's hands get cold, so the team placed the pockets on her lap, where her hands naturally lay. >> i love it. it's going to be good. >> my advise vaes is to remembei that your disality is an honor not a burden. >> reporter: in 2016, tommy hilfiger became the first major fashion designer to launch a line for people with disabilities. he says, for him, it's personal. >> i learned through having children with special needs that autistic children sometimes don't necessarily have the dexterity to button buttons and zipper zippers. and we are very well aware of the fact that wearing something great affects your self-esteem. >> reporter: the line is called "tommy adaptive," and it includes pieces for ildren and adults. >> what is great about this is, you don't have to worry about buttoning the button. tou don't have to worry ab zipping the zipper.

magnet and velcro. this is an example of, like, a men's shirt. magnetized. it's the same quality, it's the same fabric, and same design as we offer to everyone else. >> reporter: others epping up, too. last year, target's "cat and njack" children's line be offering adaptive clothing that's also "sensory friendly," no uomfortable tags or rough seams that could bother a child with a senry processing issue. it's the type of progress open style lab is pusng for. >> there's a huge consumer set that has just been ignored. it just makes sense for brands to care. >> reporter: in mid-august, with just a few days to go, the teams were busy finishing up their pieces for the final showcase where they would present their work. on the day of the big event, the residents of riverside rehabilitation traveled to parsons in their new garments. roxie gassette in her wrapes >> hi! thank you! >> reporter: ada stewart in her jumpsuit:

>> ada! you look so good! >> this is the most... the bestd >> reporter: aanda rosario in her rock & roll jacket. room and celebrated their accomplishments. creating clothes that were fashionable and functional, raising the awarenesbout the importance of inclusivity, and bringing the joy of style tr evyone. >> sreenivasan: according to the world bank, about 15% of the world's population experience ecme sort of disability. that number is ed to rise as the population ages. but more than ever, technology is helping to improve independence and accessibility for people with disabilities, and the advent of 3d printing technology is accelerating that

progress. just this month, ia furniture announced a partnership with non-profits for their ne3d add-ons to make their furniture accessible-friendly. in canada, that technology allowed a canadian outdoorsman who lost a physical ability tote cr device to help him find it again. earlier this year, newshour weekend's christopher booker brought us his story. r eporter: this trail in the canadian rockies is known to locals by the name "bragging rights." riding it takes a mixture ofcr stamina aneativity and a tiny pinch of crazy doesn't hurt either. the trail is nearly two heart- pumping mis of rocks, roots and narrow passages through the foothills of the canadian ary,ies just outside of ca alberta. but for christian bagg, riding these trails is something else entirely: freedom. and it's all because of his basement-born invention that he calls the bowhead reach. >> i could exercise, but i struggled finding something that was just fun. >> reporter: as a youn the alberta native took full advantage of the outdoor wonderland that is the canadian rockies. then cama catastrophic day

during the winter of 1996. >> i was in a big air competition, and i landed the wrong end up. i knew instantly that i ras zed. i couldn't walk, i couldn't feel anything. >> reporter: the fall had broken three of christian's vertebrae and partially severed his spinal cord. >> the nerves were connected in such a way that-- like, my lghs, my legs ththings were going on. so, they wou spasm, like, wildly all the time, like, to the point where it would pull my hips out of their sockets. it was horrible. so, for about two years after i broke my back, i lived a life that no 21-year-old should live. like, i couldn't work. i was on tons of drugs. i had to sleep in the fetal position. otherwise, my legs would, like, kick out and shake. >> reporter: this agony lasted two years, until a surgeon made a dramatic suggestion: he could sever the remaining part of gg's spinal cord, the procedure would end the muscle spasms, but al eliminate any chance, however small, that the young man might ever walk again. i so, we did it and i woke up

and no spasms anarted my life, my new life that day. all that was wrong was me was that-- was that i was paralyzed. and it was, like, amazin >> reporter: bagg spent his new life much as he did the old. tdoors. immersing himself into the world of adaptive sports. he learned how to cross countrye sit-ski, h sky diving and became an avid rock climber. but he says he longs to be back moving through the mouain trails on his own. >> i wanted to be able to venture and adventure, as opsed to knowing that something was always going to be okay for me. o>> reporter: at the timef his injury, bagg was training to become a professional machinist, learning how to build custom parts for the university of calgary's engineering department. but he also brought these skills home, setting up his own pe basement.shop in his so, when did you start thinking about the bowhead? >> reporter: pretty early. like, five years after i was injured, i started thinking about how to gbi back mountain ng. >> reporter: for years, he built different iterations of what would become the bowhead reach. nearly 25 different versions of the bike, all performing wit

limited success. buttwo years ago, his basem experiments took a giant leap forward with the arrival of a 3d printer. it dramacally accelerated his ability to prototype and test new components. what used to take weeks to build by hand could now be printed in a matter of hours. all these pieces here have beent 3d-p? th everything black, yeah, which >> reporter: is is a carbon fiber? >> yeah, so it's-- it's-- a carbon filled nylon. ut the real breakthrough wasn't printing. it was discip. >> oh, no! endure the mountain terrain,h e bike had to be rigid but hitting rocks and stumpwith a stiff frame, christian often ended up, upside down. developing wt he calls an articulating framework, something that allows the bike to lean as the rider moves their torso, the front wheels function like knee joints. so, if one area of the tround is highhan the other, the bikes maintains lance. so, if you hit a tree stump or rock, the bike won't tip over.

>> when i that breakthrough of it working, then other people sort of recognized that this was cool and neat. p >> reporter: oson who noticed was j.p. middleton. last march, middleton went skiing in the very same mountain where's christian had crashed all those years ago.t >> i wf a cat track at pretty high speed and there was a little lip at the end id it that i dn't anticipate and when i came to a stop, i, you know, couldn't feel my legs anymore, so. >> reporter: the 36-year-old e.m.t. and volunteer firefighter had shattered parts o vertebrae and severed his spinal cord, leaving him paralyzed from the waist down. >> you know, i could see the mountains from my hospital room, and i thought there's just no way i'm going to be able to make it back there. m nay wheelchair. how can you possibly live in the mountains. >> reporter: but one day, while looking out his hospital window, middleton saw something. it was christian bagg, who had gotten a hospital and was commuting to work on his now entirely functional bike. >> the next morning i was in rec therapy and i said, "hey, kim, there's this amazing bike i saw.", and she h, that's christian. he just works downstairs in the hospital. i'll have to connect you guys." >> reporter: with the help of a gofundme page, middleton was able to remodel his house,

making it wheelchair ready, and to purchase one of christian bagg's bikes. it when i saw the sticker price on the bike, it's- high. i looked beyond, and there's stumps and roots and grass and rocks, and i sat there and, you know, a tear rolled down my eye. when the bike arrived i put evan on my lp and bombed out the back through the woods over the stum and it was just the most phenomenal feeling. >> this trail system. this is right behind your house. how often do you come out here. >> eve day, evan loves. >> bag's bikes are still yment.ucted by hand in his he currently has six ders to fill. does it still feel strange to be out here? >> no, it desn't feel strange anymore. i would say, lie, it's pretty easy to fall ba i'd say, like, it's pretty easy to fall back into this. becae it's so amazing and it's-- and i think it's prettyik natural, for-- from being a human, wanting and-- and needing this. you can't overdose on this.
