Writing From Washington -- Last month, a hit squad sent by a Mexican drug cartel brazenly broke into the homes of nine police officers in a ranching town in northern Mexico. They kidnapped the officers, piled them into a convoy of SUVs and sped off into the night.

After being summoned by local authorities, troops from Ciudad Juarez, 80 miles to the north, located the convoy and fought a running gun battle with the kidnappers. When the smoke cleared, 21 people were dead, including six policemen who had been tortured and murdered before the soldiers could save them.
