It fails to consider the possibility that Ziegler’s being sane after the shooting is an indication that he was sane at
Why this is right
Any time we see a Flaw answer choice phrased fails to consider / overlooks the possibility we can ask ourselves, "(assuming they never addressed this), would it weaken if true?" Would it hurt the author's argument if we said that Z's being sane after the shooting indicates that Z was also sane at the time of the shooting? Definitely! That directly attacks the validity of this author's conclusion. This answer is sort of weird angle on the Unproven vs. Proven False. We knew to be mad that this attorney had never presented any evidence to support the notion that Z was insane at the time of the shooting. But it's even more shameful to present no evidence given that there is acknowledged evidence that Z was sane after the shooting. What this answer is expressing is the idea that, "Given that we know Z was sane after the shooting, our default position is that Z has always been sane. The onus is really on Z's attorney to talk us out of that default position, if she wants to contend that Z was insane at the time of the shooting." It's a pretty unreasonable demand to prove minute by minute that someone is sane. If they were sane two days ago and are sane now, then that probably indicates that they were sane yesterday. Anyone saying otherwise, needs to give us a reason why we shouldn't just be assuming constant sanity.
Skill tested: Flaw · how this choice captures the argument's function is the move to repeat next time.
