There shouldn't have been any significant damage to the kids, which is what this should be about, if after discovery it was handled properly. Apparently it was the adults that actually caused the damage afterwords by making a big deal out of it with the kids instead of only with the adults that should have insulated the kids from the significance of it.
If the sentencing guidelines call for 6 years in jail for this particular violation of the law, then committing that crime 8 times means 48 years. Old math, old saying. Do the crime 8 times, do the time X 8.
