Tails does little to stop this sort of attack. You really need things like isolation, memory randomization and highly audited or better yet formally verified software to counteract the risk of hacking techniques. Tails doesn't use any of these things really. Qubes uses sophisticated isolation techniques, OpenBSD has full memory address space randomization and there are a few formally verified kernels but I think none of them are available to the public. LE with hacking tools is actually really bad news.
