Why should we care about the welfare of people who cross the border? If someone wants to enter the USA legally, then that person can, on their own, find out what items to bring for the trip.
Of course if they enter illegally just shoot them.
We need to deport or imprison ALL illegal aliens, including their anchor babies, seal/secure the border with armed troops, a fence and a wall, and have a lethal response to anyone who tried to re-enter illegally.
