TUCSON - Some surprising news came from the United States Border Patrol.

The Patrol has purchased 1,000 guns that fire non-lethal paintball or pepper pellets. The goal of a target practice session was to hit the white rag at the end of a hall with paintballs. Border Patrol agents may soon use paintballs to defend themselves against smugglers along the border due to an increase in violence.

Surveillance video from an incident last year in El Paso shows a Border Patrol agent retreating after people pelt him with rocks. Some could argue the same about being hit by a paintball without protective gear, where a projectile from a paintball gun leaves a small welt on the flesh.

Small welt or not, human rights activists say it is a bad idea, even for a line of defense.
