Any flight terminating in the US is the wrong direction for these fuckers. For the vast majority we shouldn't need a plane unless the plan is to dump them in Southern Mexico so they don't come right back. I mean I'd be ok with helicopter rides, but the deterrent need not be that draconian. Just imprison repeat offenders for a little white, then dump them back in Mexico. Making their families ransom them should remove some of the economic incentive and defray the cost of policing them a bit.
