I don't know, man. I'm not a statistician, I'm just going off what they reported. I thought we all kinda agreed the CDC was one of the last reputable parts of our government.
It's an obvious public safety risk, seeing as the government takes action to mitigate the risk everywhere it gets icy every single year. Besides that, if we are placing anecdotes above official reporting, I only really know about this danger because my dad had a friend who was young and healthy who died from smacking his head on the sidewalk after slipping on ice.
I literally don't care at all what people do to resist ICE. Go buck wild, you won't hear me complaining. I'm literally just saying that characterizing this as a silly little prank is lying when the intention is obviously to cause real physical harm. I do hope that this doesn't lead to innocent people getting hurt though. Odds are they just salted it the next day anyway.
