''They're busting into a man's house, his castle, and they know he has hearing loss,'' Matthewman said.
But prosecutors contend Wilk ambushed the officers that morning, saying he was obsessed with police officers and stockpiled guns for just such a day.
Prosecutors have said Wilk repeatedly indicated he wanted to harm police officers for what he saw as unfair child-pornography charges against his partner, Jones.
''No, the defendant didn't know the day they'd come,'' prosecutor Neil Karadbil said during closing arguments. ``No, he didn't know the time, but he was ready when they did.''
Wilk has simply made up excuses for his actions, Karadbil said, criticizing the defense's contention that Wilk suffered from severe hearing loss and AIDS-related dementia.
Wilk suggested Jones use the same defense after Jones' was arrested, Karadbil said.
''He thinks he can explain away everything in the case,'' Karadbil said. ``He thinks he's the smartest man in the room, but what he is, more than anything, is a liar.''
If convicted of the murder charge, Wilk could receive the death penalty.
The panel of eight women and four men began deliberations just after 3:30 p.m. Shortly after, the jurors asked U.S. District Judge James I. Cohn for a transcript of Wilk's testimony. Cohn told jurors there was not a copy of the transcript available for them and to rely on their recollection. The jury will resume deliberations today.
