I also stopped using the light rail in LA because there isn't any serious enforcement against people riding without paying or the homeless insane. 1 out of 3 times I ride the red line, there's people with mental illnesses shouting at the top of their lungs and homeless people sleeping and taking up whole benches. The gold line is somewhat better, which is the one that I take every day, but I witnessed enough angry mental patients screaming and threatening people that I just didn't want to be subjected to it on a weekly basis. There were times where I called the police because there was some maniac on the platform shouting obscenities at people as they disembarked the train, and rarely did they show up. One time they did, and I saw them drive him around the corner and then drop him off around the block.
