I have extensive experience with my local law enforcement on this issue, and let me tell you, they simply laugh in your face when you even mention the words "illegal immigrants". Our local police chief says that they have no jurisdiction on the issue of illegal immigration! What a lie that is! It's just their excuse for not having to do anything about it.
I know that you doubt much of what I say, but it's all true. Law enforcement here in Nashville, TN wants nothing to do with illegal aliens. I think that others who live here can back up my story. Better yet, call up radio talk show host Phil Valentine and he can tell you much more.
Try reporting to the Feds... maybe you'll have more success.
There is a legal thingy in relation to lacks jurisdiction. Sorry if you don't like it. Again, try to change the law.
You know... only state police can cite you for speeding on a state highway, not a local PO.
