There are people who illegally entered the country spending months languishing in detention. An estimated 37,000 people, for periods oftentimes of 5 months or more. Why not just speed things up and send them back as soon as possible? Then there's also the issue of punishment. Those caught reentering after having been caught for illegal entry before are sentenced to a year in jail typically, more if they have any type of record in their past criminal history. Those caught illegally entering a third time can get a very long sentence, maybe 6 to 10 years. Are these punishments excessive and cruel? Strict enforcement of immigration law doesn't necessarily require long sentences. In fact the way it has been for the last 20 years, it has basically been a crapshoot if an illegal immigrant is even going to get arrested or not. Picking out a few of them and handing out a harsh sentence isn't really doing justice or keeping the border strictly enforced. Like someone once said, "Certainty of punishment is greater deterrent than the severity of punishment"
