I don't know about that.  The feds will go big just for funzies sometimes.  A friend of a friend of mine got busted a few years ago for importing exotic tropical insects (beetles the size if your hand) without a permit.  The postal inspector called in the feds because the package was making noise.  The feds sent a full swat team to the guy's house and raided his place of business, confiscating all the computers.   Why?  Because they could.
