Call me wild and crazy but I'll be watching for the news story when they lead you downtown in cuffs (and bulletproof vest) while an angry crowd screams murderer and spits in your face. Your home will be besieged with protesters, the media and every form of nutjob imaginable to haunt your family and friends. If the DNA results come back as lower primate you will likely only be charged with felony animal cruelty, but probably lose your home, guns, job and the right to vote. Should the results come back as a level of homo sapien classification, the charges will only escalate and the pain level even more intense, for you and yours. After the criminal case is concluded, the raft of civil actions will commence, effectively wiping out any remaining assets you have worked years to accrue. If the kill occurs on federal lands, amp up the ante exponentially.
Then, a few years later while you're standing on top of the bridge railing, looking into the murky water below, a sparrow alights beside you and without a sound you hear the words, I told you so....
