Clark Lindsey is disappointed that Dennis Tito hasn't followed through on his pledge to invest in space tourism, and cites his congressional testimony:

He declared that the "only big problem that stands before myself and others who want to do this is the regulatory risk.”

There was one other big problem standing between at least him and investing that he didn't mention (though it may not have happened yet at the time of his testimony). Eliot Spitzer and the SEC have been hounding him (whether fairly or not is unclear to me), which can be quite distracting from a number of other activities.

In any event, whether he invests soon, or later, or never, he still did a great service to the industry by being one of the triggers that resulted in the legislation being passed this year, opening up more opportunities for investment from others.

The "hounding him" link appears to go back to "transterrestrial.com"

I think it would be fair to allow Tito some time to make his investment decisions.

It might, but there were specific investments that he was interested in that he's backed off from, for the reason stated. It's not at all clear how long the SEC will continue to harass him, or when, if ever, he'll be able to get back on track.

The law may be written, but the regulations have not been yet.
