Demonstrative aids
show · educate · routeDiagrams, models, and illustrations that explain testimony — aids to understanding, distinct from substantive evidence.
What this type commonly supports
- Nothing by themselves — they illustrate what witnesses and exhibits prove
How the gates bear on it
The distinction
An aid explains; an exhibit proves. Mislabeling one as the other is the recurring fight.
Relevance / § 90.403
An inflammatory graphic meets the balance like any other showing.
“Relevant evidence is inadmissible if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of issues, misleading the jury, or needless presentation of cumulative evidence.”
The governing units, loaded whole
The recurring failure modes
- An 'illustration' that adds facts no witness supplied
- Letting a demonstrative into the jury room as if admitted
Software, not a law firm. This page teaches how Florida's evidence gates generally bear on this type — legal information, not legal advice, and never a prediction about your evidence. Whether a particular item clears the gates in your case is judgment work: an independent Florida attorney can review it and bill you directly. The five-gate frame lives on the Evidence Command Center.
