His "manifesto" makes it clear that he does not fear death, it does not state that he is seeking death.
Oh geez... I dunno...
Additionally, just because a suspect is in a suicidal mindset doesn't mean they have waived their Constitutional rights. Lethal force should be a last resort, not the operating mandate. Why exactly did they need to force him out of the cabin less than hours after discovering he might be there? There was no risk of hostages being injured so why exactly were they hurrying in there demolishing a cabin. At worst (and certainly the least likely scenario) there was a kill order issued seeking him not to be taken alive, at best they were being a bunch of reckless cowboys.
Under some people's mindframe as long as it happens "over there" they don't care. I'm severely disappointed that people don't have a healthier skepticism of government agent actions. Also, along those lines, that by questioning those government agents you somehow sympathize or agree with the accused...
So it seems to me that "some" people don't like the idea Americans suspected of terrorist activities being killed by drones without any trial or due process, but they're fine with someone being killed by police on U.S. soil without a trial or due process.
What a weird and fucked up world we live in.
