HOULTON, Maine — As a mother of two teenagers, Kim Matthews said, she knows a lot about the Internet.

“My children are constantly on the computer,” she said Wednesday, pausing between downtown stores. “They’re always surfing the Net.”

But Matthews acknowledged that technology is evolving and that neither she nor other parents can be too knowledgeable about the dangers on the Web.

The Houlton resident said she was pleased to hear about an Internet safety and awareness presentation the Houlton Police Department is launching for area parents.

Beginning at 6:30 p.m. Tuesday, Dec. 2, Officer Steven Nason, assisted by Officer Ezekiel Collins, will give the presentation in the cafeteria at Houlton Southside School.

Police Chief Butch Asselin said parents have critical responsibilities in keeping children safe.

“Law enforcement alone cannot keep children safe on the Internet,” he said. “Communication and knowledge [are] the key for parents when helping their child avoid the pitfalls that exist within the Internet.”

Asselin said the presentation will provide tips, information and guidelines for parents to share with their children.

Citing statistics from the National Center for Missing and Exploited Children, Asselin pointed out that more than 30 million children in the United States use the Internet and that a child’s online profile can be viewed by anyone.

Matthews said she had recently heard about the session and would encourage parents to attend.

“Better safe than sorry,” she said Wednesday.
