Did the lawyer even have a strategy? Well, he didn't do much. But maybe that was a calculated move.
Is this a fair result? Think of the record on which SCOTUS decides this-- there might be enough there to cause people to question the fairness of the final result.
Machner is the way this is done in WI: a post-conviction hearing at which trial counsel has to testify, in order to make a record as to whether things were done for strategic reasons or as a result of error. Ineffective assistence of counsel does not equal malpractice, by the way. But we still have a conflict between human nature (not wanting to look like a fool), candor to the court, and duty to advance the client's interest. Of course, you're expecting to lose at the Machner hearing-- it's about creating a record for appeal, most of the time.
Note that there's hindsight bias in play here as well-- this case was 6 years old by the time it went to SCOTUS.
IAC claims are hard to present: creating the record, doing the appeal, and passing the test are all tricky.
The reason the judge's testimony is irrelevant-- the question is answered de novo, without deference to the trial judge, so the standard is whether it would have persuaded a hypothetical judge.
Possible exploit: did counsel tank the case in order to create a great record for collateral appeal.
SCOTUS: the 7th Cir's test would often lead to reversal even if counsel's performance was flawless, so the test is bad.
Anyway, here the guy is competent to stand trial, but he has some issues. The court doesn't state a rule about how competent you have to be to run your own defense.
Lesson 1: you can forfeit your right to counsel, and it doesn't take that much to do so.
Lesson 2: systemic delays in the government or state gaming of the system might get you a dismissal on speedy trial grounds, though.
Lots of states are moving moving away from childrens' codes to juvenile justice codes. KS seems to be more rational about this; it's unclear how WI squares this with Winship.
