The DOJ has some statistics out. Numbers of the kind that we weren't supposed to see under Obama.
There are 45,493 foreign-born inmates currently in BOP custody, of which 3,939 are U.S. citizens (either naturalized or derivative). Of the remaining 41,554 foreign-born inmates (aliens):
o Approximately 22,541 (54.2 percent) are aliens for which final immigration orders have been issued for their removal;
o Approximately 13,886 (33.4 percent) are aliens who are under ICE investigation for possible removal;
o Approximately 5,101 (12.3 percent) are aliens still pending adjudication (in other words, ICE has charged these aliens as removal cases, but a final disposition has not yet been reached); and
o Approximately 26 (0.1 percent) are aliens who have been granted relief on the basis of asylum claims.
That accounts for around 24% of the 188,000 or so inmates in the Federal system. The national percentage is 12.5%. So immigrants are overepresented at double their numbers.
Now it would be truly interesting to dig deeper into those numbers. 81,000 of inmates are there on drug offenses. Another 30,000 have been locked up on weapons, explosives and arson charges. 15,000 are there on sex offenses. 14% of the inmates are Mexican. We really need to start rethinking immigration.
