Final answer:
Charges against Ernesto might have been dropped due to constitutional issues obstructing the trial or the influence of the justice system and public perception of the defendant's background.
Step-by-step explanation:
The charges against Ernesto might have been dropped due to several potential reasons based on the context provided. One possibility is that the constitutional issues could have led to the obstruction or cessation of the trial procedures, which in turn might have made the prosecution's case unsustainable.
Another circumstance might be related to the justice system and the public perception of the defendant's background, which could have influenced the decision to not pursue the charges further. For example, in historical instances such as the Sacco and Vanzetti case or the Miranda rights case, charges or convictions were influenced by both public opinion and constitutional matters.
