Who's in charge here? And who should be?

First, Sheriff David Clarke acted at a news conference like he was somehow in charge of investigating the fatal accident at O' Donnell Park.

But in today's story, County Exec Scott Walker, a champion finger-pointer who never accepts responsibility for any bad news, appears to be running the investigation.

Is that an improvement? Is that appropriate?

Doesn't this seem like the time for an independent investigation of what caused a county-owned structure to fail? Scott Walker is the county executive, hardly a neutral observer.

Can't we do this right?
