The poll found that Americans have different comfort levels with various scenarios in pursuing potential terrorist activity. For example:
_71 percent favor surveillance cameras in public places to watch for suspicious activity.
_58 percent favor random searches involving full-body scans or pat-downs of airplane passengers.
_55 percent favor government analysis of financial transactions processed by U.S. banks without a warrant.
_47 percent favor requiring all people in the U.S. to carry a national ID card and provide it to authorities upon demand.
_35 percent favor racial or ethnic profiling to decide who should get tougher screening at airports.
The first three scenarios already are legal; the latter two are not.
