A question of trust

Here's one for the selinux list: a thread just started on the CentOS list, about whether the encryption tools from upstream were trustworthy, given the revelations from Snowdon in the last six months. That, of course, leads to the question as to whether selinux, and its base policies, are trustworthy, given they were written by the NSA.... So, why *should* we trust it? mark "no, I do not have the time or energy to audit and comprehend the implications of all of selinux's policies myself"
