I can see the checks and balances argument. My biggest gripe though is with both issues the Mayor can pass the buck.
With education, I don't see how the mayor can pass a buck he never possessed. With our current setup, the buck is fully in the lap of the school board and superintendent.
The main thing re: education that I hold Curry accountable for is/was leading, or not leading, the City Council to put through the referendum to raise money for our public schools. He can also be a cheerleader that the community looks to for our schools and the value of education. But, other than that, he should be grateful he doesn't have to get an earful about many of the issues coming before school boards today. It would be a full time distraction, especially with the addition of DeSantis's agenda regarding "Don't Say Gay" and not teaching about slavery, etc. in a way that might offend whites. This, along with renaming schools after Confederate leaders (heck, Curry can't even get Confederate monuments removed

)
Crime is a different story. First, Curry ran on crime as an issue central to his mayoral agenda so he put himself front and center in the line of fire. Second, he controls the budget for JSO (for which he does little to nothing to create transparency or accountability). Third, he also has some control over other resources that can impact crime such as neighborhood investments (e.g parks and recreation), social and mental health programs funded by the City, job and youth programs (see Kids Hope Alliance), etc.
