I do not they can consistent with the Constitution.
While some have argued that things like the "no fly" list constitute an unconstitutional abrogation of freedom of movement, existing legal doctrine unfortunately seems to support it.
No, it does not. I suggest you review the pertinent case law. Are you a lawyer?
Also, it's not clear that those other three-letter agencies are categorically more competent and less intrusive than the TSA. (Look up the NSA's warrantless wiretapping program, for instance. Or look at the Christmas bomber, who evaded the FBI and might have succeeded if it were easy to get a better bomb through the checkpoint.) The TSA is just more transparent and visible to the public.
The TSA is not transparent, though it is visible. I repeat: the intelligence community has been quite effective at preventing terrorist attacks on US soil. TSA, on the other hand, has proven itself completely ineffective at anything other than dog-and-pony shows and harassment.
