Your -1 on "killing Americans without trial" is an allusion to the NDAA. The NDAA is a smoke-and-mirrors issue; the problem isn't Obama's NDAA, but rather the 2002 Bush AUMF, which is still in effect. NDAA's enemy combatant language limits the powers already granted to Obama by the AUMF.
Obama also appointed Sotamayor and Kagan to the Supreme Court, but that doesn't fit nicely into a message board narrative about civil liberties.
It is a drastic overstatement to call Obama a "disaster" on civil liberties.
Restrictions, huh? Do you think those might be related to the NSA storing and processing everything that happens on the Internet?
I sure am glad there are restrictions in place though!
 Yeah. Who knows. Let's just not go there.
