In weak cases, lawyers from either side will try to confuse some of the issues. But the rules of evidence, criminal trial procedure rules, and the presiding judge can make this difficult. Also, even though good research about jury deliberation is limited because they are conducted in secret, I recall (from memory) that research shows juries are pretty good at detecting when someone is trying to deceive them. Further, in trials, the opposing party gets a say in the matter too. If one side says something deceptive or deliberately confusing, competent lawyers for the other side will point this out and attempt to correct the record, possibly turning the jury and the judge against the deceptive lawyer.
