User blog comment:The Demon Archer/Zoom is not a Speedster/@comment-28835160-20151115011823

I've read the comics and you are right, but the show isn't always going to be 100% accurate to the comics. While the Flash has been really good about being accurate to the comics it still has to go its own way. Epicshawty is correct. He has to be a speedster to steal speed. Only one possessing the speed force can do such a thing.
