No one is telling them how to feel. If they "feel intimidated" by the protests, they can continue feeling that way. This is solely their problem and nothing needs to be done about it.
Absolutely no statistics, or analysis paralysis is needed to make these claims.
Are the vast majority of protests allowed? Yes.
Have any protests been shut down? Most likely no. If at all they have been, probably can count on both hands.
Have some disruptive people been removed and charged? Yes.
Hence 99.99% is a reasonable number and no further justification is needed. Also this shows that protests are a non-issue.
No expertise is needed to report what is observed. The fact of the matter is almost all protests are allowed to take place without consequences.
