I think you're reading something into my comment that isn't there, probably because the nature of this site lends itself to reply opposition. I'm not against police enforcement. I'm trying to say, this desire you speak of isn't visible.
While what you say is true about lower income residents, plenty of community groups who perform outreach to lower income communities show up and comment against the police. Pro-bono law forms, homeless volunteers, soup kitchen folks, they all claim that low-income people dislike the police.
All I'm saying is that this disconnect is frustrating. Fundamentally low-income people are just being spoken for. On this site it's high-income people who claim to know what low-income people think, and in public meetings it's community groups who claim to know what low-income people think. I myself grew up low-income but am high-income now and I'm wary (my skin color is dark) of but overall positive (I mean what's the alternative? Lawlessness?) toward the police, but again I'm a high-income earner in a high-income district.
All I can say with certainty is that cops are expensive and that nobody seems to be excited enough to secure the tax revenue needed to fund them. If the only point of contention here was policing attitudes that would be one thing, but transit agencies don't even have enough money to maintain service let alone hire officers.
