I would have to see the bill he is talking about. There have so many iterations of this that I can't really have an opinion on this one way or the other until I read it myself. But, saying I am willing to give up my rights as a citizen for the greater good is never good optics and will sour a lot of people on him that were once on his side.
After reading it again you are probably right, but he probably should have added a "but" at the beginning of that line. FISA and how it can be used against normal citizens is a hot topic to some people, including myself, so he probably should have been more clear.He's talking about himself not anyone else.
