The "evidence", I suspect is that their informed analysis doesn't match well
with Craig's desires. Very strong evidence, indeed.
We need to remember that it took Cellular telephones 17 years to be
approved, and about 15 years of that had nothing to do with technical
issues.
The proponents started off asserting that their current state of the art
devices would never cause interference -- I've read their filings -- and
they were made to look foolish, since they tested later devices than the
ones they based their claims upon.
They'll get it right eventually, but I suspect that something more akin to
the NAB's counterproposals will need to be used, where broadcasters (and
other licensed spectrum users) will retain the ability to shut off
interfering devices.
We need to remember that the initial push was that the current devices of a
year ago would NEVER cause interference. In the first test, they failed
miserably.
Now, think about how this stuff will work in an emergency. Imagine
one-to-one phone calls and emails "Are you alive" interfering with ESSENTIAL
emergency information that normally would be delivered to hundreds of
thousands. And, if your VOIP phone call doesn't get through the first ten
times, up the power, after you are an individual, you own the airwaves, and
you want your phone call to get through. Who knew it would take a TV
station down?
Intel doesn't have enough money in the bank to pay for the damages in a
single market.

I believe you mean the "MSTV/NAB" tests, where there was evidence of faulty
test design and political gerrymandering. Subsequent independent tests, at
the same locations, proved the use of inadequate test criteria but could not
overcome the political bias.

What evidence do you provide to support this allegation?

Again, what evidence do you posses to support such a conclusion in this
instance? Much of what the FCC and MSTV conclude relative to white space
issues is supported by testing done at he CRC. Clearly the FCC are short on
technical resources but they do have those skills and they do appear to have
the ability to adequately perform such limited tests.
The White Space coalition did not find fault with the FCC testing and
stated: "they would work with the commission to resolve outstanding issues
with regard to expanding access to the Internet"

FCC: Prototypes Fail 'White Space' Tests
The FCC's Office of Engineering and Technology has issued two reports on
initial measurement studies performed on low power RF devices that could be
operated within unoccupied television broadcast spectrum known as "TV white
spaces."
