Videos of minors committing crimes are on the media all the time.
Juveniles are protected from having their identities released in some cases, but not all. Doing something in a public venue on public transportation system ought to get them on the 6 o'clock news.
So, "they" know that they are minors, correct?
This would imply that "they" know who they are, correct?
So "they" have made arrests???
