New York City moving homeless out of subways

New York City responded to increased violent crime in the subways by pushing out homeless people who were living there.

Does this make sense? I wonder what fraction of violent crimes in the subway are committed by homeless people. My guess is that it is minuscule, because the factors that could make you homeless have little to do with the factors that could make you violent. My guess is that this is simply a way to "arrest the usual suspects" and show that you're "doing something about it."

If the city's night-mayor has any evidence to the contrary, I'd like to see it.

I also guess that an increase in the number of cops patrolling in the subway will change little, because criminals that commit crimes for profit and can think about it will simply commit their crimes where no cop is present. However, the patrols might result in catching more of the criminals who are mentally incompetent to plan like that.
