Who saw this on CNN, just now? Greta reamed this environmental lawyer, who said that the WTC was unsafe. It took him a while to get around to mentioning who he thought was responsible for this. The stupid lawyer started talking about the firefighters without masks and blamed the FF unions (and one other party), just as a video clip played that showed a large number of firefighters all wearing masks. Greta smacked him speechless.
Yes, it is dangerous, but the PPE is provided, as evidence by the video clip. I always love watching liberal fools get blasted by facts.
