The U.S. legal system does not empower prosecutors in this way. They are free to provide quotes out of context, of course, but defense counsel are just as free to provide the missing context, and neither actually gets to make the decision to convict.
Don’t underestimate a federal prosecutor. Perhaps we need a new saying: “If you give me six lines from the US Code, I can get a plea bargain from the most honest of men.”
