"OTMs" are "other-than-Mexicans": illegal aliens who are from Honduras, Brazil, Yemen, Communist China, Saudi Arabia, Iraq, and other fun countries.

"DHS lets go 'other' illegals" gives us this fun statistic:

Nearly 70 percent, or 68,000, of the more than 98,000 OTMs detained so far this year were released almost immediately because of the government's inability to return them to their home country and a lack of detention facilities to hold them while here, federal authorities said.

Nevertheless, we're informed that our homeland "security" administration is working on doing a better job.
