What exactly did this tweet mean ? Any clarifications?

I was just going through some articles, where this was brought to my attention. I’m not exactly sure what is/was being suggested, so I thought I’d ask for a clarification, granted I may have missed an explaination prior to the last couple days.

Thanks Much,

Zooko is a good guy. Perhaps he is referring to law enforcement through other methods such as exchanges. Latest news regarding Alphabay and Shadow Brokers may have something to do with it.
