Shadow, the Minneapolis police dog who was stabbed several times while trying to apprehend his second suspect ("Hunt comes up empty," March 31), deserves a great deal of credit. Politicians make our laws, but it's the police, including the K-9 cops, who put their lives at risk to enforce those laws. Passing a law is one thing, but taking a "bite" out of crime while getting stabbed in the process is real public service. JERRY T. JOHNSON, BLOOMINGTON
