Why is the news of a coverup almost always an outrage modifier when it comes to crime? Because the statute of limitations can be problematic. Not to mention how evidence can grow cold after several years.
Remember, certain media outlets had to force these issues in New Orleans, and any idictments at all are a testament to (mainly Federal) investigators working against almost all odds to uncover the truth.
In the macro sense, this is especially true regarding beatings, arson and other elements of intimidation and terrorism. Systematic coverup allowed terrorist organizations like the Ku Klux Klan to run unchecked across this nation for decades, and required intrusive Federal enforcement when local communities and state agencies refused to cooperate (through either tacit agreement with the terrorists, civic ambivalence or out of fear of reprisal).
That history will always remind me to respect the intentions behind Civil Rights laws and hate crimes legislation. But I wonder if there could just be a way to extend the statute of limitations for conspiracy or collusion to cover up a crime?
I'll let the resident attorney answer that one.
