Who are those guys?

It's a phenomenon in the Netherlands. The men in white suites.
The rumors fly. Every time disaster strikes they appear.
What did they know and didn't wanted us to know. Is Uranium found after a plane crash? What were they doing after the fireworks disaster? Is it the secret service or are they Venusians?
I can plaster the page here with Dutch hyperlinks but I won't. Find out for yourself. (Dutch = witte pakken.)
But wait a minute they're in my office so let's get the blip out of here.
