This was a jury note in an actual gun and drugs trial. Can you guess what they really wanted?
A quick google search of D+A brought up this:
|D&A||Drug and Alcohol|
|D&A||Depreciation and Amortization|
|D&A||Design & Analysis|
|D&A||Delivery and Acceptance|
|D&A||Dry & Abandoned (oil & gas industry)|
|D&A||Deals and Allowances|
Obviously, none of them mean DNA, which is what the jury sought. It's further evidence that trial lawyers cannot take any juror's understanding for granted.
