Recently I saw a homeless man urinating next to a busy elevator at the North Hollywood subway station in Los Angeles. Not something you look forward to seeing during or morning commute to work, or any other time. Just as he finished his business, a transit security officer walked up to him and tried to arrest him. The homeless man scuffled with the security officer and the officer had to use pepper spray on the man. Two other security officers ran to assist their partner so I assume they were able to subdue the homeless man.
I am advocate of mass transportation, specifically light rail and subways as they are the fastest and most efficient. I like it mostly because I am saving boat loads of cash now due to the high gas prices. It is also nice to know that it is beneficial for the environment.
Unfortunately, there are some negative aspects to public transportation. Crowded buses or trains, rude people, smelly people, uncomfortable seats.
And homeless people urinating in public.
