"Stanford Report" quotes Professor Jayashri Srikantiah

"There has been more than a tenfold increase in border enforcement expenditures in the last decade or so, at the same time as there has been a drastic increase in the amount of undocumented migration," Srikantiah said. "The more complicated the U.S government makes it to cross the border, the more profitable it is for smugglers or traffickers to take people across," she said. The net result has been more deaths at the border; in 2005, there were 450, she said.
