Why is one person voting not guilty a deadlock?
The jury votes 11 to 1. If its not unanimous, that is the jury verdict. If that means they cannot convict because it isn’t unanimous, then thats the answer of the jury.
Isn’t a jury that can’t reach a unanimous verdict, given their answer?
"If the jury cannot agree on all counts as to any defendant, the jury may return a verdict on those counts on which it has agreed.... If the jury cannot agree on a verdict on one or more counts, the court may declare a mistrial on those counts. A hung jury does not imply either the defendant's guilt or innocence. The government may retry any defendant on any count on which the jury could not agree."[8]
