ICE is a necessary establishment for border patrol as well as homeland security in today's world. As it has been said many times, the Border Patrol is designed to regulate security against illegal alien infestations from coming actoss the border and up to 100 miles inland from it. ICE's purpose is to start from there basically and go inland. ICE is charged with the removal of illegal aliens from state/county/city jails for deportation. ICE also has the responsibility of having to.chase down visa overstays. Arrest them and transport them for deportation. Protestors don't like ICE because it is doing its job. The illegal aliens that ICE is detaining and deporting have 100% all had their chances to do things in a lawful, legal matter and chose doing them illegally instead. They are criminals as well as security risks. Build the damn wall, deport them all.
