At approx. 47 mins, Casey is wearing a visitor sticker for pediatric ICU, but Elliot doesn't appear to need one.
It should've been a 4th (unreasonable search & seizure) or 5th (self-incrimination) Amendment violation when Det. Stabler & Dr. Warner approached Evelyn on the sidewalk & asked to measure her hands, to see if they matched the bruises on her daughter. Evelyn had not be formally informed that she was a suspect, she had not been arrested (the measurement provided the evidence to then arrest her), she had not been told of her Miranda Rights, and she had no attorney present. One would think her defense attorney would've used those facts to have the measurement thrown out in court, yet no attempt to use those violations of her rights by police, was presented in court.
