I will agree with you on citizen involvement. I think that part of it is how it's approached. Right now, the announcement given is to "Report suspicious behavior...". What's that? Will people on the train understand what that is? Will both the passengers and the DART staff agree?

Will DART staff do anything? I've tried to use the elevator at Mockingbird Station and gotten some very dirty looks from the homeless people who were literally camping in it. Which, frankly, I don't care because you shouldn't set up your camp in a public elevator. The DART staff at the station were studiously ignoring the issue even though they were working on the escalators near by. They left it for me, the passenger, to deal with.

I think that a rotating announcement, "Report drug sales and/or use...", "Report open containers of alcohol...", "Report people asking for money, cigarettes,....", etc., would work much better.
