I didn't know they made those bikes like that for kids. And, it is illegal for them to ride on the street. I don't know how loud they are, but if they're loud enough, it would piss me off too. I lived in a neighborhood once where teenagers rode dirt bike with no mufflers up an down the street. I moved because of them, I was only there a month. The ******* with a gun confronting little kids was wrong, there are other ways to address problems like that. But that dad letting his kids ride in the street is an issue too. In a congested neighborhood like that, I don't think that's appropriate, but that's just me. Can't be much worse than a basketball hoop! These old people around here sometimes babysit there grand kids, toddlers. They can be noisy, but surprisingly they don't bother me, they have no ill intent, not like the adults. I'm sensitive to noise, so I guess it depends on how loud they were.
