This question was already answered earlier in a very satisfactory manner IMO.
You don't have to go looking for them, they will come to you.
In my last post, we have 55,000 of them in prison. We already know they are illegals, we don't have to go looking for them. They came to us. Rather than feed/house/cloth them, deport them.
Then we come to traffic accidents and offenses. I would wager that there are illegal aliens involved in these incidents many times a day in every city of any size in the US. I work full time as a paramedic and am not talking through my hat: I see it all the time. Not only are these people illegal, but now they have caused significant damage and possibly bodily injury to someone and they have no insurance to pay for any of it (That's OK, I got it, just roll that into MY insurance rate). The other people involved will never be able to recover anything, but we can give them a consolation prize: the illegals are deported.
Then of course there is the question of employment. Allegedly the reason they come to this country. If I am not mistaken, we already have a mechanism in place to ask to see certain credentials before someone can be hired. We should take this a step further and provide some way for the prospective employer to verify the information given. For example: if someone gives a social security number, it could be verified that this person was born in such and such a place and is in fact alive or something like that. If eight people are using that SS number then it is pretty obvious that at least seven of them are fakes. If the SS number comes back to some guy that was born in Davenport Iowa, yet the guy with the card can't speak English, you might want to think about this. If it can be determined that an employer hired an illegal alien without running them through a background check, then the owner of the company or CEO of the corporation will face mandatory jail time. This includes people who pick up day workers at Home Depot or the local nursery.
Let's also use some common sense here. After 9/11 we had a big hubbub by the lefties about profiling. This is hogwash. When dealing with people you can certainly tell if they can speak English and if they can, is it heavily accented. If either of these apply, you ask for ID. This obviously is far to easy for the average liberal to understand. Sometimes the person will pull out valid ID and everyone goes on about their business, so what ?
There are many venues where illegals attempt to enter the mainstream. Want me to be really un-PC ?: hospitals. They come in to a hospital for medical care with no intention of paying for it (That's OK, I got it, just roll part of that into my medical bills so my insurance rates can go up so you can get yours). I can hear the lefties crying now: oh but you can't deny them medical care !!!!!! Ok, I agree with you. If they need emergency medical care, we give it to them. If it isn't an emergency, we put them on a plane to elsewhere within the hour. If it is an emergency, when they are able, we deport them. Before you go off half cocked about this, do you think that if a known murderer comes to a hospital that they give him a pass because he is at a hospital ? These people are criminals. Felons in fact. Why are we giving them a pass at the hospital ?
Then another sacred cow, the lawyers office. Switch to the Spanish channel and note the personal injury lawyers advertising in Spanish. These people want to take someone else's assets through the use of force, but they can't even speak the native tongue. So, before you can participate in the American legal system, you have to prove you are a citizen. If, in the proces you fail the test. You are deported.
Obviously anywhere that gives out my money to people who didn't earn it (government give away programs). Governemnt housing, food stamps, Medicaid, Social Security, School System............................
But, as mentioned, this isn't ONLY about the Mexicans. People from other countries certainly come here to enjoy what America has to offer. How many students do we have at our universities that come from nations known to sponser terrorism ? How many students from other countries come here and engage in protests which involve spitting on and burning our flag and denouncing our leaders ? How many American kids would like to take their place in college but can't afford it ?
Build it, and they will come.
Hell, I see cars and trucks driving around town everyday that have stickers covering the back window announcing what Mexican state they come from.
This ain't rocket science.
