Rick Santorum Urges 'Profiling of Muslims ... and Younger Males'

Rick Perry called for privatization of the TSA at home and improved intelligence-gathering capabilities abroad.

The Texas governor, during Tuesday's CNN debate on national security, criticized the Obama administration for degrading intelligence services.

Rick Santorum said profiling is needed. "Muslims are people you look ... and younger males," he said.

But Ron Paul condemned his fellow candidates for "careless use of words" in seeking to step up security.

"We're digging a hole for ourselves. What if they look like Timothy McVeigh?" Paul asked.

Herman Cain said the profiling question posed by CNN moderator Wolf Blitzer was "oversimplified."
