Witnessed bullying - did I do the right thing?

So today I was in my bedroom when I heard kids yelling in the street. All my windows are open. I listen and I hear one kid say “fight me you pussy ass bitch!” And I hear the other 2 kids encouraging the one kid to hit the other. There’s a total of 4 kids.

So I look & this 12 year old boy is hitting and yelling at this other boy in the street. The other 2 kids were laughing and encouraging it. The boy who was getting hit ran to his porch and was crying, and the other 3 kids ran across the street to the school park. I couldn’t believe what I just saw in front of my house.... I was furious!

I quickly run outside & ask the boy if he was ok. He was upset and wouldn’t talk to me so he goes inside and his mom comes out so I tell her what happened. Me and his mom walk over to the kids who did this and told them what they did was absolutely wrong & that they need to apologize to the boy they were yelling/hitting at and that violence is not the answer. They are lucky someone didn’t call the cops (my husband is one, but wasnt home) The victims mom chewed them out, thanked me, & went back home.

They said “fuck you! don’t tell me what to do!” Which made me even more mad. Their parents showed up and I told them what I witnessed. The parents didn’t even care, they laughed at me and said boys will be boys!!!! And told me that they taught their kids to fight back during a fight” They didn’t even acknowledge the fact that their kids were bullying another child. They didn’t even say a word to their kids or punish them - which is why I assume their behavior is the way it is because of their lousy parents.

Did I do the right thing by speaking up even though nothing was resolved?? I couldn’t just sit there & act like nothing happened. I told the kids that violence isn’t the answer, that they can’t sit and lie about it because I saw it all happen, and that they need to apologize for their actions. If I wouldn’t have spoken up nothing would have been done, the child’s mom had no idea it even happened.
