That illegal immigration almost requires ID theft is obvious.
If undocumented immigration almost required identity theft, the clear response would be to make it easier for people to legally immigrate to this country.
…that isn’t necessarily the case for illegal immigrants.
To quote the New York Times:
And experts say the available evidence does not support the idea that undocumented immigrants commit a disproportionate share of crime.
Analyses of census data from 1980 through 2010 show that among men ages 18 to 49, immigrants were one-half to one-fifth as likely to be incarcerated as those born in the United States. Across all ages and sexes, about 7 percent of the nation’s population are noncitizens, while figures from the Justice Department show that about 5 percent of inmates in state and federal prisons are noncitizens
Note that those who argue that illegal immigrants aren’t associated with higher crime rates leverage the decreasing crime rate overall, not illegal alien criminals vs citizens and legal immigrants.
Ridiculous generalization of all the arguments presented by the Con side in the debate you linked. A lot of them provide data taken from over the years, while the Pro side features articles from the great Breitbart that present half-truths or baseless claims.
