Depends where you are. Readers of the UK weekly "Amateur Photographer" are aware that this is not the case in the UK.
The London police work on the assumption (apparently under orders from their bosses) that anyone taking photos in a public place where children are present is a paedophile, and should be arrested and their equipment confiscated until they can prove otherwise. The police advise that anyone wishing to take photos in a public place where children might be present should get police permission first.
In Manchester one reader was almost arrested because he took some architectural detail photos, and just happened to have a tax office as a back drop. The police took the line that photographing any government buildings was now illegal under the prevention of terrorism act.
And a reader out with an AP columnist near the Houses of Parliament had a run in with the police becaise some of his photos happened to include the spy cameras.
