Pack'd Like Sardines

I have been reading yet another story on illegal border crossings between Mexico and the United States. The story details the meetings of families and acquaintances across a chain link fence near San Diego and the U.S. government's plan to further fortify that barricade. I can't help but think of fences put up in order to protect highways and interstates from "illegal" animal crossings in front of vehicles. If you, for some reason, should want to follow my reason, so it goes: a group of people moves into a portion of land, pushes others out of that portion of land, then draws imaginary lines on a map and calls them borders of that portion of land; they then build barricades along that line because that line has become part of history after being an imaginary line for hundreds of years; after this hundreds of years, this group of people believes that they may prevent the migration of another group of people. So all of this may sound over-simplified, but most things must start at the base before building. We must be careful lest what we think is freedom turns out to be greed.
