Law school 101 will tell every 1L that the biggest gift is for a criminal to take a plea of life imprisonment for murder. http://www.cnn.com/2015/01/05/politics/dzhokhar-tsarnaev-trial-plea-deal-fails/index.html and below NBC news article that is critical of trial: http://www.nbcnews.com/news/crime-c...hokhar-tsarnaev-begins-jury-selection-n277561 But Uncle Sam (Justice Department) wants to take this to death penalty which may see the Boston bomber walk. There are too many instances of reasonable doubt that the defense could put up. The whole entirety of law school are cases of just how often the feds lost or got it wrong when they decided to go to trial or failed to take a plea. Trials almost overwhelmingly favor the defense. On Perry Mason the good fight and unlikely cases are won, but in the world of jurisprudence in the USA, it's a bit more tricky. Only in America.
