Show me where Fish & Wildlife agents job description states their jobs are to bust rapists, drug dealers, etc. These agents are doing what their job demands and what they were trained for.
And, smugglers, no matter what is smuggled in, are 'real criminals' that skirt the legal process to bring in items through avoiding inspection, quarantine, tariff, and legal documentation such as legitimate importers do by process of good business. By not making these inspections, and subsequent busts, this country would be at risk of a slew of diseases that are causing major suffering to animals and people in other countries where our imports originate.
