I assume the logic was:

1) People demand the government be accountable for their failing to protect them

2) Government responds by increased giving the appearance of protecting them, since that creates more lowest-common-denominator sense of feeling safe than the government actually protecting them does; votes protected

3) Complaints of "security theatre" don't alter the above - they just have to wait until people have forgotten their fear while very slowly, bit by bit, without it being noticed, stop doing the nonsense

Or put simply: "terrorists win"
