how is the government involved with homeless people?

There are several different, albeit vaguely unhelpful ways that the government is involved with homeless people.  Firstly there is a portion of the US government's funding that is put aside for the homeless population in attempts to get them shelter and food.  The funding is also there in hopes that welfare, and other state funded assists (food stamps, etc.) can get to them.  The government is also occasionally involved in the building of homeless shelters and other places for homeless people to reside in times of need (these places are often regulated and limited to a certain number of people).  Aside from these two factors the government is also responsible for getting homeless people of the street, a lot of the time this involves police and further legal reasoning - disruption of peace, or another such violation.  Hope this helps!
