They can kill people on American soil.
I doubt that. The white paper published did not specifically say it one way or the other but that would be unconstitutional. Even if terrorist are here illegally they have always been treated as a law enforcement problem. Most here found it incomprehensible that Miranda rights were given to the underware bomber. Should any targeted assassinations be conducted within our borders that would be a different situation. I know the left and right would not stand for that. I look forward to congress flushing this out but I sincerely doubt it would cover persons within US borders. This presidential finding will be severely limited.
Realistically can you imagine the left thinking this would be ok let alone the right?
