>While you try to figure a way to sidestep that and change the subject, keep in mind that the fact is nobody knows how many illegal immigrants are not paying taxes, or how many illegal immigrants are paying a proper amount on taxes, so your statement above is crap. I know, it's the convenient crap response that most liberals use to try to sidestep the issue, but it is still crap.
A certain kind of those paying is easy to find - you and I could write the appropriate SQL statement over one beer (each), and so could the law.
Now you imagine some good reason why the agencies never wrote that SQL statement.
