Again, this would set a dangerous precedent. By all means, I can look at these punks and I can tell they have some "ain't shyt" parents or parent/guardian. HOWEVER, there are cases where the parents are either unaware of what their kids are up to because some kids can be sneaky and keep up a facade. Also, there are parents who are really trying their best, but the kid is just gone.
Blaming the parent every time their kid does something bad is just like giving the parent credit when their kid is doing good... And there are plenty of "ain't shyt" parents who have kids that have never gotten in trouble and did well for themselves.
Start with the repeat offending children. If you lay the hammer on repeat offenders, maybe the 1st time offenders may take notice. People claim they hate guns, well be extremely tough on those who use them illegally.
