The guy used as much force as he could to try to kill dozens if not hundreds of people. Excessive force doesn't exist in that situation. You do whatever you can to stop the guy. Shoot, stab, bite; whatever it takes. Only an America hating DUmmie would whine about the terrorist's rights and "excessive force" used against him. I can only imagine chopping him up and feeding him to pigs might qualify as excessive, and only then because I'm lazy and would skip the chopping bit.
