Is this "struck" a metaphor related to ""three strikes" law?
st197)In an effort to speed up the criminal justice process, defenders and prosecutors have established the plea bargain. It refers to an agreement between the prosecution and defense that the accused person will admit a plea of guilty to a crime, provided that other charges are dropped
provided that and a reduced sentence is recommended to the judge. While the Supreme Court has approved of plea bargaining in general, extensive use of this tactic has been an issue with many politicians who demand that those convicted should serve longer sentences. In response, they proposed the "three strikes" law, which says that after having been convicted of three felonies, a convict must receive a life sentence,
whether or not a plea bargain has been struck.
No. 'Strike a bargain' is a reasonably common expression.
