The police union has acted absolutely disgracefully, deciding to dishonestly blame the mayor, exploiting the tragedy to demand he resign and reappoint Guiliani or perhaps Joe Stalin, or anyone more amenable to the vicious, brutal, ineffective, old-fashioned over-policing they prefer in any case. They also seem to believe they have a right not to be criticised under any circumstances, ever.
I'd despise them for the lack of regard they show their dead comrades, but actually I hate more their total contempt for the democratic process. Fuck them. Anyone who signs their evil, despicable petition should be instantly fired.
