I blogged about this measure previously, so I'll keep today's missive short and sweet.
I saw today's Chronicle article from Chip Johnson opposing Measure NN. I obviously agree with nearly everything he said in terms of the city using the money well, but I do support NN for two reasons:
First, I think it's useful for the city to have money earmarked for public safety. I realize that it will be misspent terribly, but I do believe at least some of it will get to the desired destination. And, I believe public-safety spending has the potential to snowball by creating a virtuous circle of gentrification.
Which brings me to the far more important point.
I view gentrification as Oakland's only hope for improvement. In thinking about taxation, I believe that parcel taxes aid the cause of gentrification. This is because parcel taxes are regressive, so they punish the poorest in the community and encourage them to leave.
Oakland has too much poverty, and much of its crime stems from this. So, Measure NN is a good antidote to this in two ways. It may directly push out some crime through policing, and it will certainly encourage some people to move, as they will be unable to afford the parcel tax.
