"It used to be you got beat up on the playground," Plants said. "Now pictures are exchanged by friends, and after a breakup the pictures still exist and are distributed."
Juveniles don't understand - and many adults don't, either - that once such pictures are posted on the Internet, they are there forever. And law enforcement agencies are getting better at discovering them and using them as evidence.
"Even if a picture was sent to you and you didn't want it, it would be illegal to possess it," Plants said. "Once kids learn they can go to jail - juvenile jail - for up to a year, I think they'll cease and desist.
"Kids have no idea about the consequences of taking pictures of yourself, how dangerous that can be," Plants said, referring to nude or suggestive photos. "Or how badly it can affect other teens."
Parents, he said, might not be aware of how common sexting is.
"I would say four out of five, or at least three out of five junior high and high school kids are doing it," he said. "Parents would be shocked if they inspected their kids phones and computers.
"And if they are not doing that, they better start," he said.
Plants hopes that if passed such legislation would encourage victims of sexting to come forward and parents, teachers, counselors and others to bring it to the attention of law enforcement.
According to the National Conference of State Legislatures, at least 19 states have enacted bills to address sexting by juveniles.
