On the big screen at Eisenhower Junior High School on Wednesday, the former Arkansas coroner shows a photograph of an arm, a huge chunk of its blown away in a drive-by shooting. The 10-year-old was asleep in his bed when he was shot.

Nawojczyk (pronounced Na-voy-check) pushes the remote control and the image changes to a leg dangling from a coroner's yellow body bag. The appendage belongs to an 8-year-old accidentally shot by his older, gangbanger brother.

"There is only one rule to live by," Nawojczyk tells his captive audience. "Do right. If you do right, right will come to you."

The images are shocking to the teenagers, but Nawojczyk believes they are successful.

"Sometimes it takes a slap in the face to get the message across," Nawojczyk said after the presentation.

His work with gangs has been featured in numerous national news programs and as part of HBO's "America Undercover" series. The piece, titled "Gang War: Bangin' in Little Rock" won the CableAce award for best documentary.

Nawojczyk was invited to Utah to participate in the annual Law Day Celebration. He agreed to come so long as he could speak to a group of junior high age youths.

In his presentation, Nawojczyk admitted that when he first tried to get to know gang members, he suffered from a syndrome he called BDWG - big dumb white guys.

"I thought everyone that wore baggy clothes, listened to hip-hop music and carried a pager was a gang member," he said.

He soon learned that the problem crossed racial, socioeconomic and religious boundaries. He came to understand, too, that most kids are good and it's only about 1% who cause the problems.

The message reached many of the students.

"He was very influencing and kinda cool. He showed us that it is OK not to do the bad stuff," said eighth grader Ryan Filipe. "With peer pressure it's tough, but you have to think of the little kids picking
