The Guardian is publication reporting the information. If you click the link at the top, open the website, and read the article, you will see who is quoted as making the claims.
The quotes seem to indicate that they don't care about drones. The context surrounding the quotes is all The Guardian's.
He emphasized there was “no known threat to the public at this time”.
Etc...
Then quotes of one word end quote two words not quoted, then a few more quoted words. Or a sentence that's clearly drawn without context.
Typical modern reporting. The people being quoted don't have the time to care if they were lied about.
So, yes, if you click the link, you'll see who is quoted making the claims, but there is no reason to think that they actually made those claims. Only that those people don't care enough to stop their workday and refute every piece of media trash with their name in it that probably didn't even make it to their desk.
