There is none. Have at it--it aids the healing and it might change things.
We of the webs are entitled to throw accusations and guilt for whatever and to whomever we deem fit.
From Dan Abrams, who knows a thing or two about criminal defense and prosecution and jury selection (regarding Bernie Madoff, in this case):
But unless I am sitting in the jury box armed with that power I, and any other nonjuror for that matter, have no obligation, moral or legal, to embrace that legal fiction (presumption of innocence by public).
The same applies, for example, to hearsay evidence. It's generally inadmissible in court, and yet most of us live our lives based on what people we trust tell us they heard or learned.
Some claim that, because legal banditos like me refuse to presume every defendant innocent, the prospective jury pool is polluted, thereby making it impossible for jurors to presume innocent a defendant in a high-profile case. Malarkey. That is why we have jury selection.
The goal is not to find jurors who necessarily know nothing about a case, but to find jurors who can fairly evaluate evidence and determine guilt or innocence. No question, extensive media coverage can make the selection of a jury take longer. In a worst-case scenario, a change of venue would be the remedy. But defense attorneys who complain about poisoned jury pools are often really just saying that they think prospective jurors are lying when asked what they've heard about the case in the media.
We, of the webs, will not likely be asked to determine the guilt or innocence of Jared Loughner or Sarah Palin or Glenn Beck or Rush Limbaugh or any of the hundreds/thousands of others who have brought political rhetoric to the level it is today. Just like with any family tragedy, we question, we blame, and we discuss how unfair it all is. Unlike a family tragedy, we have media and politicians to hold accountable. This dialog is valuable--it heals and it may, in fact, cause those in power to consider their words and actions next time.
That, DU, is what those of us on the political interwebs do. And we should continue to do so.
Edit: misspelling.
