Maybe. But take a good look at young people today, especially young women, and their behavior with their cellphones. They stroll across the street oblivious to traffic. A fight breaks out and all the bystanders whip out phones to record it. Did you see the video of a young woman in Spain observing the running of the bulls and leaning against a building at street level chatting on her phone, who completely ignored the bull that rounded the corner, stopped, turned back, and attacked her. A T-Rex could escape from Jurassic Park, come rampaging down the street, and all the young people would behave like Japanese tourists in 1950's B movies, freezing in their tracks to take pictures.
Total absorption in their hand held devices. Situational awareness: zero. Automatic first reaction: take a picture. They'd be too busy taking pictures to get on the lifeboats on the Titanic. The Darwin Award is being seriously devalued.
Also, other people were filming during the shooting. There is video from people who were out in the field and filmed everyone running and screaming during the shooting. She’s definitely not the only one who filmed.
