Question: If Myers switched with the paramedic (as shown at the start of the next movie) and the medic couldn't speak because his larynx was crushed, why didn't he take the mask off to show Laurie it wasn't Myers? At the end you can see that he was able to have full use of his arms and hands when he got out of the body bag, then got up after he got hit by the van and when he was pinned he raised his hands to her.
Answer: Because they didn't think there'd be another movie, as this one appeared to be Myers' swan song, as it should've been.
Answer: And seriously, only a Michael Myers could survive all of that trauma. It was a Hollywood ending that could go either way and if the ratings and the income was savory enough, the paramedic dies! So yes, maybe this paramedic was a Myers relation.
Chosen answer: There is no answer to that. Its simply bad work by the writers. They never tried to explain that. You could perhaps assume shock had prevented the paramedic from immediately taking the mask off. Unlikely though,.
