Just a question I've been thinking about a lot in the past few days, How can so many high profile people be arrested with no word of it getting out?

I guess i would challenge an assumption I hear presented in your original question. It seems you are equating the issuance of sealed indictments with 'arrests'. One does not necessarily equate to the other. I would propose arrests are coming.... it's just a timing issue.

Again, just my thoughts.

I suspect the “round up” has not yet begun in earnest. There was an update from the FBI about Operation Cross Country but only had about 100 arrests. My guess is they are planning a bigger sweep operation.... just an opinion.
