When SVU gets to the sight of April's car wreck, the first responders tell them that there were no survivors. But they would only say this if they had found a deceased body (or bodies) inside. The car was empty, so instead they should have said that no bodies were found.
The McManus Institute's address USA listed as 114 East 57th Street which is in midtown Manhattan. However, the office window views clearly show it to be on the ground floor of a building in a rural or suburban area.
In Pallister's first interview with his lawyer present with Stabler and Benson, the lawyer refers to April as "the defendant." At that point, April had not yet been charged with any crime and was the one alleging his client of rape. The word he should have said was "complainant."
