This has had the opposite effect of what you seem to be implying. It's something that's come up quite frequently in discussions of jury nullification [1]. Jury nullification being when a jury ends up voting not guilty, even when they believe the defendant guilty, generally because they do not find the law (or possibly the punishment) just.

For decades a rate of about 5% for hung juries was typical. In more recent years some jurisdictions have seen more than 20% of cases end in hung juries. [2] Some have seen this as evidence of a rise in jury nullification, but others have argued that it's due to the 'CSI Effect' [3] with these individuals believing that, because of shows like CSI, the standard of proof required for a conviction seems to be rising - along with a reduced weighting given to things like circumstantial evidence.
