The border fence, one of the proposals for deterring illegal immigration, is a plan that by itself will do no good. Why? The same reason that intelligent people know that just locking the doors at night is no guarantee that their house will not experience a break-in. The locks only prevent honest people from entering. Dishonest people will break-in to homes, or break-in through the fence.
What the fence buys is a little time. Just like locks and alarms buy time for those in a home. In a home, when someone breaks in, you gather the family into the most secure location you can, arm yourself so that the intruder will be stopped if he continues, and call the police. Anything less, and you risk being the one that “when seconds count, the police are only minutes away.” The country needs to treat this the same way. People that cut through a fence to enter the country should be viewed as potentially being drug runners, smugglers, terrorists, or any other kind of evil people. They are attacking the borders of our country, and should be repelled with all available force. The fence — along with technology to warn of the attack — should be used to give enough time to deploy force. We have a national guard, we ought to use it.
