After watching the movie "Which Way Home", discuss some gaps in immigration policies and possible solutions. President Biden has halted construction on Trump's wall and has a more open policy towards immigrants than Trump did. We are seeing the highest number of unauthorized immigrants in the past 2 years, many of which are children traveling without their parents. Reference the film and characters when answering this question so that I can tell you watched the film. Is there even a problem that we need to solve?
