The no-fly list is an instrument of political repression.  The FBI No-Fly List has 81,000 names, the Terrorist Watch List, which is another list the airlines consult, has 875,000 names (and that was as of 2013).  If people are deemed "too dangerous" to fly, then surely they are "too dangerous" to drive, indeed to walk free and should be charged with whatever criminal activity they are suspected of "going to commit".  I note that our own politicians are too much political cowards to disclose even the number of Canadians on its list, let alone their ethnicity (take a wild guess as to which ethnic group appears most often, ....no not white Anglo-Saxon males).
