Not sure setting up roadblocks in neighborhoods is a good idea let alone legal. That's a bad scene from a bad movie.
I'd really be annoyed if stopped by some guy asking me any questions on the street or in my car. I'd just tell him to get the fk out of my way. Don't know what authority they have to just set up road blocks to check people's citizenship. We do not live in such a country, and never have. This will be tested in court too.
This is how we can go down the road of authoritarianism.
How about if we set up road blocks to check for legal guns?
And they bitch because of the healthcare mandate.......
Gimme a fkng break.
