Lawyers are not magicians. What questions should he have asked that he didn't? You keep insisting he should have done something but are unable to come up with even one suggestion or example of what he should have done.
ETA: You also need to realize that when you call defence evidence, you open yourself up to cross examination, which can hurt your case. A lawyer interviewed on CHML today discussed how the decision to call a defence and/or put a defendant on the stand is often very, very tough.
I don't think I have been judging Pillay since I thought DM was guilty of murder right from the first few days of evidence: cell phone/burner phone/tattoo/leaving the truck in plain sight evidence. Everything else (that he may or may not have asked) just seemed to fade to less importance to me.
I don't think I could armchair quarterback a guess as to what else he could ask until I can hear the judge's instructions on convicting for first degree. My opinion is a conviction on second degree is the absolute best they could hope for. My impression is that the crown headed off the "veterinary crematorium" excuse for having an incinerator and that might have been one of the defence attempts to discredit premeditation (if that is even still relevant in this case for a first degree conviction).
I suppose similarly they could come up with an excuse for the change in clothes...
One loose end for me was the actual planned barbeque and when/if that occurred and if Smich was even invited (since he wasn't at the house very often according to AM). His pictures of roasting food (was it sausages?) and fireside furniture made many here point to premeditation (for both). Added note: I'm not saying DM's team should even raise it though....
