Well that's what the guy writing the blog is saying. Nobody else is saying that. But you seem to believe it so let me make sure I have this straight. After shooting the taser at Scott, Slager halts, ejects the spent cartridge, pops in the new cartridge, has the taser taken from him by Scott who then shoots Slager so that one dart goes into his upper torso and one dart into his calf - about four feet apart. Does that pretty much sum it up?
Speculation about whether Slager got taxed aside, what 101stAirborneVet said in his earlier comment about the moment of decision to shoot, and the psychological kinesis or inertia that involves, will probably sum up this case. At :17-18, Slager is justified in deciding to draw and fire. The only charges he should face should have to do with the fact that he looks to have failed to suddenly reverse himself in the chaos of change, and instead followed through on his decision. Whether that amounts to guilt on any charge is in question, given the science of decision making and action under extreme stress.
