The correct way to write the quote would have been ">The rioters this week haven't shared the same [...] determination", where the [...] shows you're editing: by implication you're not doing so misleadingly, but the reader gets the chance to check whether they agree.
The problem with your post as you wrote it is that you appeared to be making the claim that the word "same" immediately preceded the word "determination" in the source you were quoting. Which isn't true. This matters not because the difference is important in this case (we all agree it's not), but because people think poorly of you and your arguments when you make false assertions through carelessness (they think you might do it again and it might matter next time).
