Oakland School Shooting

[awty]

You might be fined, but it's incredibly unlikely.  

In this case one of the details of the story suggests that some precaution was taken.  The kid was searching for ammo online.  Interestingly enough, though some states stipulate that  person be 21 to purchase specific types of firearms, they can often purchase the ammo, legally, at 18.  That's part of what makes the humble .22lr the standout in trace data.  The customer need only say "It's for a single action long gun".

I lean on securing ammo myself, heavily, with four kids on the house.  Honestly, though, I don't think my squirreling away the squirrel gun is why my kids wont and haven't blasted anybody - it's because I raised them in gun culture.

Along with those limitations on the purchase of ammo is the fact that in a purchase online it's pretty easy to fake your age. If you got your hands on dad's credit card you're are suddenly old enough.
