So where exactly is our side?

[usa today]

Interesting story on Fox all afternoon

They are calling for the National Guard to help stem gang violence in Chicago , And yet they refuse to send the guard to the border?

Whats wrong with this picture

Also I call into question the Posse comatatus(sp) , you cannot use the guard for a police action on the border but its ok in Chi?

Also isn't that the purpose of our military in its original sense? to protect the country from invasion?
Why do we even need a military if we cannot use them to protect our borders.

I'm really confused here on this one.

We maintain an armed force to ONLY fight foreign wars? And to hell with protecting this country.
