Subject: Re: We Don't Know Who We're Deporting
If I have a population of say, 100 illegal aliens and if say, 2 of them are predators, then even though only 2% of the illegals are predators I've made the US safer by deporting all 100 illegals.

And if you have a population of 100 native-born citizens, and 2 of them are predators, then the illegal population is no more dangerous than the native population. And you don't make the U.S. any safer by deporting the 100 illegals than you would if you expelled the same number of native-born citizens. You're not gaining any safety by picking illegal aliens instead of anyone else - the only reduction in absolute crime comes from just having fewer people.

And of course, the rate of crime doesn't go down. If the illegal aliens have the same rate of "predator-ness" as the general population, then the overall rate of crime will remain the same whether you deport or not.
