If they were legal at the time, then no, he was doing his job, congress would be responsible. To clarify, PRISM and related programs are completely legal via the FISA bill (http://www.govtrack.us/congress/bills/110/hr6304/text). They shouldn't be legal, the supreme court will likely strike them down as unconstitutional, but they are LEGAL.
As for torture and extraordinary rendition those things were ACTUALLY ILLEGAL. So yes, President Bush and/or his administration should be held responsible for them.
