When trying to puzzle this out, I see the media is overwhelmed with posturing and wide-eyed horror and indignation on all "sides" of this issue. From "the usual sources", it's hard to tell if we are baking young children in ovens, or if MS-13 is infiltrating our nation with elementary-school killers.
Have you all had any luck in finding a detailed accounting of the situation, and the context, from any reputable sources? Data, history, policy comparisons, that sort of thing?
