Do skateboarders have some sort of omerta code?

My son is a boarder - and in my opinion the issue isn’t really about their safety - its about the property damage. My concrete gets chipped from the trucks - he bought a new rail so he wouldn’t use the steps because I said he couldn’t.

But a bad bunch of boarders is a bad bunch of boarders.

Yeah, I couldn’t come up with a shorthand for gang mentality that wouldn’t get some people riled.
