I really don't understand the library hit. I mean, if I was doing HIGHLY illegal activities, generating big $ and knew that the only key to my prosecution was my laptop, I would only do work in a highly secure facility. Like a single metal door that couldn't be opened from the outside when locked. That's just me, though. I'd be paranoid about it. Especially after the sentence:

“The only way for them to prove anything would be for them to watch you log in and do your work.”

Instead, he's like "ooh, what's that sound". Tackle, snatch, guilty, life in jail.
