I think her remark is way over the top and she would have been better off keeping her mouth shut.
But I do have to say if a terrorist intends on coming into the country...killing/injuring maybe 100's or 1,000's of men, women, or children just to make a statement, or for some butt hurt political or racial agenda...I really don't care what they do to them if they're caught.
If someone has basically no regard for my life, the people I love, and the lives of others...what regard "should" I have for theirs?
