How sad. Reminds me of my 2016 visit to Chicago, after funding to mental health care was cut, and people in facilities were let out with nowhere to go but the streets. A six-foot man wearing a child's pink Power Rangers pajamas walked the streets, barefoot, mumbling... this is America, land of opportunity, and we had all these people homeless and uncared for. As you say, some can be aggressive. Not everyone welcomes assistance. To discern who to help and how is a life's mission. God help us.
