But then there is this sort of study... https://insights.som.yale.edu/insights/yale-study-finds-twice-as-many-undocumented-immigrants-as-previous-estimates https://dailycaller.com/2018/09/21/mit-study-illegal-immigrants-double/ ... One thing about the whole 'immigration' topic, that I believe is true, is that it's all being purposely muddied -- simply because of all the different 'reporting', etc... If so, then one has to wonder why that would be the case (i.e., for what purpose?)
