What I would do to increase border security is mine parts of our border. We do not need to mine the entire border; just parts of it. The trick is we can put up mines only in certain places but not the entire border; so that way it would be economical. The genius of this idea would be that people would not know Where the mines actually are. In this way it's more psychological effect because it get's people scared from taking a chance to cross our border for fear of touching a mine since nobody would know where the mine is. The only people who would know are our border guards. This would lead to less people willing to take the chance of crossing our border if they think that they might step on a mine. We can call it: "The Mystery Mines".
