To dam a river you flood the upstream portion to create a height difference in the river that your can use to generate electricity.
This flooding submerges MASSIVE amounts of vegetation which undergoes anaerobic decomposition releasing tons of methane. It’s a one time thing, but it’s actually up there when you include the expected lifetime of a hydro plant, and the fact that methane is a very powerful greenhouse gas.
I mean the officer was clearly scared for his life. I know to you and me that seems absurd, but police officers are hand-picked and trained to be the biggest cowards imaginable. Several people are killed by babies (with guns) each year in the US and that makes them logically scarier than half the shit police officers are scared of.
I can’t believe he even entered a home that had a known baby in it, it’s almost as scary as entering a school with an active shooter!
