In Bridgeport, Conn., in March, Fermin Rodriguez, 21, was charged with assault for stabbing his wife several times (after an argument over her alleged infidelity); police said that following his attack, he apparently handed his knife to the couple's 2-year-old son and said, "Now, you stab Mommy."

According to the manager of BJ's Pawn Shop in Gretna, La., a customer came in with his diaper-clad boy of about age 2 in April and handed the kid an AK-47 from the store's shelf, instructed him how to hold it in order to "mow (people) down, kill everybody," and told him that "Daddy's going to buy you this chopper." The manager, incredulous, said he took the gun back and shooed the pair out.
