John Morton, the head of Immigration and Customs Enforcement (ICE) has apparently decided on how to hold illegal aliens in custody. http://news.yahoo.com/s/ap/20091006/ap_on_go_ca_st_pe/us_immigration_detention_reforms (h/t American Patrol http://www.americanpatrol.com/) He will put them in hotels and nursing homes. All those are well know for their high security, as no on ever escapes from a hotel.
How this will save money is not known. Hotels are pretty expensive, more expensive than most state and local jails who charge around $50 a day in most areas. And, of course, it is alot more difficult to escape from a jail than a hotel. But more likely that is Morton's plan. Letting aliens escape so they are around for the upcoming amnesty.
