Children's Murders Could Have Been Prevented why after many encounters with police it takes murder to stop him?

Police are afraid to report the illegals to ICE because they fear being sued for discrimination or something. Local governments are afraid to instruct their police forces to detain and report illegals because they fear Big Sis and AG Holder will come after them. Just deporting illegals with felonies and violent convictions isn't enough. Any encounter with police should be enough to have them sent home.
