Now doesn't this story just make you want to say "Welcome,my southern neighbors!" There are thousands of unprovoked attacks by illegal aliens. I can't recall reading of one by a US citizen against them. Well, except recent Hispanic citizens from the last amnesty who prey on some immigrants.
How is this any different than an act of war?
Good question. The only answer is that Mexico always gets a free pass no matter what they do.
I always thought that INVASION was an act of war, but in George Bush's America that doesn't matter either.
