Can we ask them about the red team failure rates at
the airport and question them about when safety of
actual backscatter machines will be tested and reported?
Can we ask them when studies showing that behavior
detection works (as used by DHS) are published in peer
reviewed papers (i.e. accepted by the general scientific
community as not junk science)?

I don't discuss my travel plans with strangers but I
sure do want to know why they spend money better
than drunken sailors (no disrespect for sailors intended).
