>What kind of instances? Taking a photo? [...] that anybody photographing a public piece of artwork shouldn't raise suspicions or trigger an FBI follow-up. //
If he took a single photo he's nothing like any photog that I've ever met. Sure, they probably have tourists, art appreciators or whatever, taking photos sometimes. But, I'm guessing, they don't all get added to an FBI SAR list - so this person was clearly not "[just] [t]aking a photo". Indeed he was probably taking dozens of photos, from lots of angles.
There's too little detail of course in the story to know - that would move against the angle they're trying to sell.

This was targeted intelligence gathering, surely.
