This letter is such a joke.
''our planned 50 days cruise'' yeah right, like you really said you would stop after 50 days. The rest is just pure hogwash. For people who claim to want to bring about ''change'', they certainly use the exact same BS methods in their communications as their vaunted ''oppressors'' (''power and freedom''? How is stealing personal information giving power or freedom to anybody?).
Also, not wanting to continue a discussion that's been denied, but ''it's used because it works'' is a poor justification indeed when it comes to police affairs that none out of their district knows about, including the results.
EDIT: Oh, didn't even read the rest, they also released a torrent containing said stolen personnal information. Way to destroy any sliver of remaining credibility, guys.
