I agree. How about a little redirect, madam prosecutor, such as:
"CI Hardy, Please tell us about your medical condition."
"I've got a heart condition. Doctor says I could drop at any minute."
"How has it hampered your physical ability in any way?"
"I'd say. I'm practically an invalid. Couldn't chase down Joe Miller the first time he tried to turn himself in. I nearly died."
"How about deliver a blow strong enough to break someone's ribs?"
"I can certainly bellow loudly enough but don't think that would break a rib, no. Had offers of sex turned down for fear I'd die. I couldn't beat a stick, if you know what I mean."
"Who else knows of your condition?"
"My doctor, of course. My boss. Miller."
"How has this impacted your work?"
"I've been pulled from active duty. Stuck boring cadets to tears."
"Your honor, I submit that the defense's theory is bullocks. We can call his doctor if you would like expert testimony, but I am sure you agree that won't be needed."
Of course, the plot gods required a complication. Toss the confession, they demanded. That will mess things up nicely. Since this is drama not an actual criminal trial I have more patience. It was not like watching the OJ trial--I was screaming at the TV.
