Helping someone commit a crime should be, and is, a crime. However, helping someone in any other regard should not be considered a crime by an means. It is quite baffling to think that helping homeless people, could be a crime. If it is and if it develops to be, then I will truly be disappointed in the world.
I help feed the homeless every month or so with my youth group. And the term help can mean many things - help them financially, help them with some food, giving them blankets or simply holding a conversation with them. More often than not, the people I meet, who have nothing, want more than anything to have a conversation with someone. To know that they are important, that they exist and that they deserve some time of day to get to know and be listened to. So many people walk past the homeless as if they are invisible, and so to strike up a conversation with them means a lot more than a small bag of food does.
td;lr: No, helping the homeless should not be a crime.
