Many reasons, but one that I haven't seen mentioned is that it's a slippery slope. Whatever we allow them to do to non-U.S. citizens can and will likely be turned against U.S. citizens. Their simple argument is that the terrorists walk among us, and are thus indistinguishable from American citizens. So, they must now cast a wider net that includes Americans. We have already seen them use this rationale and, in fact, it is part of what got us here today.
