After $1 billion spent, the US has 53 miles of 'virtual fence' in Arizona. The high-tech project is too costly to extend along the whole US-Mexico border, the Homeland Security chief said Friday.
Border patrol Agent Brian Terry was killed in a gun battle Tuesday night. It could be a sign that smugglers are becoming more willing 'to just to shoot it out with agents.'
About half the money in the House plan goes toward 1,500 new border personnel. Not in the plan: money for any border fences. President Obama could sign a version of the bill in September.
The virtual border fence was supposed to revolutionize US-Mexico border security. But delays and glitches led Homeland Security Secretary Janet Napolitano to freeze its funding Wednesday.
After years of snags, work on the electronic surveillance system along the US-Mexico border restarted this week.
The viability of a high-tech barrier to detect illegal border crossers remains uncertain, after a pilot project struggles.
