A more pressing need than banning soda

In an article in today’s paper about a woman who murdered a man by pushing him in front of a subway train in New York City, an interesting fact:

There are no barriers separating the trains from the people on the city’s subway platforms

Seems like that would be an easy problem to fix. It is obviously a more pressing need than making sure people don’t drink too much soda. How about it, Mayor Doomberg?
