Final answer:
The claim that President Obama said we must treat every child in a specific way in the Mass Murder Montage is false. He has made speeches about children's safety concerning gun violence and required court hearings for undocumented children before deportation.
Step-by-step explanation:
The statement that President Obama ends his message saying that we must treat every child a certain way in the Mass Murder Montage is false. President Obama has been known to speak out on issues regarding children's safety, especially in the context of gun violence as seen in his speech following the Umpqua Community College shooting. In such addresses, he generally focused on calling for actions such as changes in gun control laws. Moreover, with respect to undocumented children, President Obama approved plans that required these children to receive a court hearing before deportation. His addresses have emphasized the necessity for reforms and collective responsibility, rather than specifying how each child should be treated.
