Cross-border attacks on agents continue, says the Border Patrol, despite changes in the way agents patrol the San Diego areas just across from Tijuana.

To emphasize the point, the Border Patrol today released a video, from Sunday morning, which shows a young man on the Tijuana side of the border nonchalantly launching rocks across the wall with a slingshot. The man slowly walks around a barren field in the area known as the "Soccer Field," east of the San Ysidro Port of Entry, picking up rocks and firing them directly at an officer, the Border Patrol says in a press release.

Several of the rocks seem aimed directly at the remote-controlled camera.

During fiscal 2007 (October 2006 through September 2007) the Border Patrol recorded 254 assaults on agents. In the 11 months since, there have been 340 such attacks.

The good news, for the agency, is that most attacks in the current year took place in the "earlier months" of the year, before new patrol strategies designed to counter the attacks where introduced.

The Border Patrol now deploys what it calls "focused and layered enforcement" strategies in areas where most of the cross-border barrages occur.
