According to KOLO, District Police Chief Steven Zipperman “says the campaign will teach students about violations of child pornography and obscenity laws that can come with sexting along with the personal consequences.”

“We’re really trying to get the message out that before you push that send button, please think about what it may mean to you — not just the criminal factor but the embarrassment, your future employment, college entrance. What you do now matters, and they need to understand that,” according to Zipperman.

A 2014 study in Texas found found 28% of students surveyed had sent naked pictures of themselves via social media, like the app Snapchat, and 60% had been asked for at least one.

“It’s a perfect storm of adolescent hormones coupled with the immediacy of a smartphone,” says associate professor and psychologist Jeff Temple, who coauthored the sexting study.

According to the police chief, the school lessons “will teach students about the dangers of sexting, including possible criminal violations of child pornography and obscenity laws and the personal consequences,” the paper reports.

“We’re really trying to get the message out that before you push that send button, please think about what it may mean to you — not just the criminal factor but the embarrassment, your future employment, college entrance. What you do now matters, and they need to understand that,” Zipperman says.

But some students don’t what the problem is — and especially why there’s criminal punishment.

One 16-year-old girl, identified only as Vivian, said sexting has become so prevalent, students are surprised the police get involved.

“I didn’t take it as much because it kind of happens often,” she tells the Times. “Students shouldn’t be criminalized for it.”
