Gallimore v. Attorney General, 619 F.3d 216, 227 (3d Cir. Aug. 20, 2010) ("While we give deference to the decisions of the BIA ... we cannot give meaningful review to a decision in which the BIA does not explain how it came to its conclusion." Awolesi v. Ashcroft, 341 F.3d 227, 228-29 (3d Cir.2003). Here, the BIA's failure to explain its interpretation (if any) handicaps entirely our ability to review it for reasonableness." (footnote omitted)).
