A Washington Post article titled "Justice Dept. concludes that no, Michael Brown’s hands probably were not up" has this:
According to the report, here is what investigators believe most likely happened on Aug. 9.
There is not evidence to suggest Darren Wilson’s use of force was unreasonable
Michael Brown likely did reach into Wilson’s vehicle and grab the officer
Michael Brown did double back toward Darren Wilson
(Boldface as shown in the original.)
The writer lists these boldfaced sentences as important points, so I believe extra care must have been taken to makes these sentences grammatically correct.
And my question is about the first boldfaced sentence: Is it both grammatical and natural to use "not" as is, instead of "no" or "not any"?
Or is this a typo?
Also, please check to see if the contracted form (There isn't evidence) is any better than the original.
