I don't think that's "editing". Last night, the sheriff said he wasn't convinced there was only one shooter. He was tired, and didn't make a lot of sense at times.
But today they came out with a statement saying they've ruled out the possibility of two shooters.
Of course there may be conspiracy theories that persist...
Wasn't the girlfriend alleged to be in Vegas at time. And when was the card used, three days at least to have parked elsewhere and maybe walked back in.
Way too much stretching for 'important parts' I recon.
