No one does on purpose. You are again insinuating that this guy in the OP for some reason put a gun in a backpack and said "yeah, my toddler is gonna be packin' heat today!" This is my main problem with your position on this matter. You seem to have some feeling that vengence needs to be doled out by government on this guy. You think everyone knowing he got his kid banned from daycare is not punishment enough on it's own? The willingness to have the state wield abusive powers to punish a guy for a clear mistake, that to point out yet again harmed no one, is simply unbelievable. Why on earth would you want government to hold any power I this situation? How can you now step back and see that exact power can very easily be abused against you for other mistakes other people may not like you personally for?
