That's not the way democrats / Marxist work ...
Asking him to resign/leave would mean he's taking responsibility for his actions. Only people with a moral compass do that...they have none...
De Blasio will find a way to deflect the blame, get the attention off him and throw as many people under the bus as possible, after all Marxist are master propagandist...
It would not surprise me at all in a few weeks we start seeing stories about the assassinated officers that put them in a bad light...
At some point they have to be aware of public sentiment running against them and will have to cut their losses. For now, they are silent, but that may change if there is more chaos in NYC. With the inauguration of the governor for his second term coming in a week, it may become untenable for them to allow di Blasio to continue. Everything is about the agenda to them, and if di Blasio becomes too much of a liability they will give him the boot to save themselves.
I don't doubt that we will see these officer's reputations besmirched in the next few days in an attempt to deflect attention.
