I think you may be missing the point, here, which is not to jump to conclusions and make racial statements like "all Mexicans are bad." However, if the statistics in the article in question are true, I'm just speculating here, then it seems like it would be a good idea to defend our borders more carefully and enforce deportation, if so many criminals have been entering the U.S. illegally from Mexico. Considering the fact that a lot of illegal emigrants are fugitives from their own countries, and that if they were not on the run from their government, then they may take the time to follow our process of naturalization. This is not always the case, however, as families from Mexico sneak into the U.S. to escape poverty. For this kind of situation, it would probably seem a better idea to become less strict on immigrants, for the best interest of the families such as these. The problem here, however, is that the U.S. may not be able to distinguish the impoverished families from the runaway fugitives from the impoverished workers who come here to the U.S. and then, victimized by continuous racism and prejudice, may be driven to commit crimes. Notice how SgtRock only gives us vague statistics that may in fact prove that a lot of the crime in some U.S. cities may be due to trouble caused by illegal aliens, but the statistics say nothing as to how many of the immigrants who come into the U.S. are actually criminals, versus how many of them are just normal people trying to lead normal lives, and if anything, pose only some small detriment to the economy.
In any case, some action needs to be taken to combat the crime which enters into our country evidently from the country of Mexico. Since illegal immigration has been happening whether we like it or not, I think it would be best if the U.S. provided an easier way for families of Mexican citizens to immigrate into the U.S. and turn them into model citizens. This would, of course, require a bit more money put into the education system, but this is something the U.S. has been in desperate need of since Reagan cut education in his term.
In addition, the U.S. needs to become much stricter on the illegal aliens, investigate the activities of the ones already in the U.S., and possibly naturalize the ones who are here but not causing any trouble in the same way that we provide naturalization for the fresh immigrants.
Finally, it may be in the best interests of the U.S. to research further into the individual causes of criminal activity coming as a direct result of Mexican immigration. I suspect that perhaps it is racism and discrimination that drives immigrants to become criminals, but again I am only speculating.
There ya go, some idealist solutions and useless speculation!
