Pope Leo Channels Pope Francis and the Communists on Laudato Si

When I watched the pope bless the block of ice (3:18) I couldn't help feeling like it was a skit from Saturday Night Live. He should be as good to the ICE agents and bless them instead of casting aspersions on the U.S. for their "inhuman treatment of immigrants." What "treatment" is he talking about? - giving illegals $1000 and a free plane ride home if they turn themselves in. The Vatican has walls and laws protecting the Vatican state. Do they "welcome the stranger" coming in with criminal intent?
