To be clear, I wasn't the one who made the comment regarding whether the laptop should have been discovered within 15 minutes.
But in general, it does an individual who was trespassing (in this case, on a network) no good to complain that other people were allowed in. There are exceptions to that for MIT since it's a university, but given that Aaron was both white and male, I don't think he'd have been able to play the minority discrimination card.
Which was exactly my point. That's why your original comment about "that laptop should've been discovered within 15 minutes" doesn't make sense.
Their network model deliberately doesn't care about an extra random laptop, until somebody complains.
