You've now posted two articles about crimes that occurred on TriMet busses/trains. How is that I TriMet issue? It's a crime issue. The past few years when "apple-picking" was spiking in NYC, no one was condemning the MTA.
In the theft article they talked about TriMet police conducting undercover work to catch these criminals. In the last article, TriMet obviously utilized their video surveillance to help aid in the arrest and conviction of a person committing some pretty gross acts.
Sounds like you have an aversion to city living, in addition to public transit.
Three drug addicts were arguing very loudly and aggressively (one started pushing the other) outside the Salvation Army Center two days ago when I was walking my dog. I watched the police come and deal with it. They should close that Salvation Army right?
