Much as I am against illegal immigration, I would not encourage snitching. It’s un-American. (Putting flameproof suit on . . .)
Let's exercise a bit of logic here, alright?
If you had a next door neighbor who regularly beat her child senseless in her back yard, and you had seen this with your own eyes on more than one occasion, do you think it would be improper of you to report her the the authorities?
Likewise, illegal immigrants are doing great harm to our country by being here. It's illegal because it's harmful - get it?
Looking at illegal immigrants in light of everything I just said, can you see how it would be a good thing for you to report them to the authorities?
