Eric and Dylan Bullies
Did Eric Harris and Dylan Klebold engage in bullying/abusive behavior? Yes. Here is a list.
Eric and Dylan shot kids with BB guns
Randy Brown's son, Brooks, said Eric and Dylan shot kids with BB guns
In No Easy Answers, Brooks Brown says that Eric and Dylan sat on the roof and shot at little kids with their BB guns. From page 63:
"I think the story that got me the most was the one they told about Halloween of junior year. That night, the two of them went up on the roof with a BB gun and took shots at little kids who were trick-or-treating. They said the kids would look around, all confused at what had hit them, but because Eric and Dylan were concealed in the darkness of the roof, they never knew. They told us about this over lunch, laughing like it was the funniest joke in the world."
Eric and Dylan superglued locks shut
On a "Rebel Mission," Eric and Dylan superglued the locks to Nick Baumgart's house. Someone also superglued the locks to the school shut shortly before the shooting.

Eric and Dylan set off a firecracker bomb in a mailbox
After chasing some kids into the Wisher house for allegedly "robbing" Blackjack Pizza, people who fit the description of Eric and Dylan tried to get them to come out with no luck. Not long after that, a fireworks bomb was blown up in the Wisher's neighbor's mailbox. (11k, p.1012)

Eric cracked Brooks Brown's windshield
On February 27, 1997, Eric Harris was at a bus stop having a snowball fight with someone else when Brooks Brown drove up. Eric threw a snowball at Brooks' car that apparently contained a chunk of ice and this cracked his windshield.
