Or, aleernatively... letting a few crimes go unsolved is part and parcel of an authoritarian police state.
Right now, we have on our 'unsolved docket' Lois Lerner, war crimes by US troops in Iraq, high treason by various top operatives violating their constitutional oaths and undermining the rule of law, thus aiding the enemies of the US, embezzlement by bankers who control the Fed, breach of fiduciary duty by BoA under the blackmail of Paulson that he would break the law... and now most recently high crimes by that French bank in criminal money laundering, in one is the biggest ever (9 billion) fine, but unfortunately, we can't find the criminal.
And that's just the US. I haven't hit one percent of the unsolved crimes yet.
Leaving a 'rule of law' nation sucks.
