To an extent, this is merely a reflection of harsh reality. You can’t prevent every crime or catch every criminal. A certain number of murders, muggings, and aggravated assaults will also occur each year, and not all of those offenders will be arrested, charged, or convicted. But the difference is that prosecutors won’t say it’s too risky to charge a mugger because the jury will hear that the victim carried her purse in plain sight, and thus vote for acquittal.
