Lafler is potentially revolutionary in that the State is now entirely at the mercy of defense counsel when it offers a plea.
Prior to Lafler, a competent prosecutor could try a clean case and present sufficiently solid evidence that any minor mistake by the trial judge would be a harmless error. Equally, by presenting an overwhelming case at trial, the prosecutor could try to make a solid case that any incompetence by trial counsel would not be [later seen as] prejudicial.
Under Lafler, however, [the same] overwhelming case which defeats a trial ineffectiveness [claim] now helps prove that counsel was incompetent in advising his client to go to trial [in the first place]. I think most prosecutors could have lived with ineffectiveness limited to failure to advise -- that [is something] a prosecutor can cure on the record prior to a plea expiring. But including misdavising is open season for attorneys opting to fall on the sword for their client which is not as infrequent as the Kennedy opinion assumes.
If I were back in the US Attorney's Office, I would think long and hard before I offered a defendant a plea bargain, ever.
