Eric's weapons?

Do you really believe that Eric's parents didn't know a thing about all those guns? I know Dylan was just an crazy idiot, but Eric seems to take shit really serious... So, really? All the videos, all the writings, and no one fucking know bout what they're planning to do?
Sorry, but I can't believe.

I find it hard to believe that nobody in their lives suspected a thing.  But at the same time, I think this is proof of how people didn't take them seriously and how much they were viewed as underdogs.  Nobody ever suspects the quiet kid, the underdog, the kid who doesn't have a big voice. It's so much easier to get away with stuff when nobody pays you any attention in the first place.

They live in a hick town everyone has guns. Going to the woods and shooting guns is considered a past time. And this was before the public was more aware of school shootings. Etc. And it's laughable you excuse Dylan as just a crazy idiot lol
