just a btw, if you saw and found believable Spielberg's new "Lincoln" movie, I think it suggests that if presidents didn't make up their own laws the slaves might not have been freed.
Now every citizen in the midst of a crime should be apprehended alive and tried, but sometimes that doesn't seem like the best choice. I mean, if a guy is in the process of mowing down theater goers or school children and a cop has the opportunity to use what tool he has, in the cops case his gun, to kill the killer before he kills one more other citizen, well then using that tool might be the cops best choice. So now we have a tool called a drone and a scenario where a citizen in the midst of a crime may not be apprehended alive in time to stop the killing of one or more other citizens, should we use the tool? If you say yes to the cop/gun scenario, then you may say yes to the president/drone scenario. To so say yes, you have to assume that in the time allowed the culprit can not be captured alive before he does his damage, and you have to suspend the idea that drones are such a pussy method for delivery death to your adversary
(apologes to female readers but if you know a better synonym for the word I resorted to let me know... I certainly don't use it with any actual gender reference).
Finally, will the right to kill citizens, be it gun/cop or drone, be abused? Killing from a distance is usually easier than having to face your target/victim eyeball to eyeball, so the question may become "does ease lead to abuse?" That suggests, "Do we have to depend on the trigger man to always be sufficiently humanitarian? or must the laws force him to be so? So we've come full circle and we're back to "law". And ease. Does the new law make it easier for the President to protect the USA? Does the USA, with all her faults, deserve protecting? Is the USA the very citizens it can lawfully kill, or is it bigger than that, or is it just the gang that protects my individual self from the other gangs at the gate who want my stuff, at least making sure I have enough oil this winter so my kids are warm.
