If reporters were there, they would have been identified.
And it is very awkward when the interns and staffers of all the democrat reps turn out to be nazis.

Yep. Too dangerous to give the reporters a chance to get close to them, but a smallish group marching quickly through tourist areas such as the Bicentennial mall, the side of the Capitol facing the plaza, 1st avenue, and then Broad, would likely be seen by a few people who would pull up the camera function on their phones. Toss a democrat into the mix to 'coincidentally' encounter the group when he is leaving a meeting where he had been speaking about the problem of racism in Tennessee, so that he could get video and post it to social media with his narrative to keep things moving in the right direction, then you just need someone other than the group everyone is focusing on to provide the news media with an identity for that group - which would apparently work out to be democrat rep Behn with all the intel and apparently keeping a closer watch on the group than Metro police (again, it is quite handy to get the planned march route in advance).
ETA: Looks like they started from the Bicentennial Mall, went to the Capitol building and posed for a bit overlooking the Legislative Plaza, then marched over to the Nashville Public Square/Courthouse and down 1st Avenue to Broad. Anybody see any other details that would fill in the gaps of that route or place them somewhere before they appeared at the Bicentennial Mall or after they left Broad? Even without a planned route being provided to Nashville police and local reporters, that's an impressive amount of ground to cover while wearing red shirts and waving flags, and still not run into police or reporters.
ETA2: Then again, looking at the map and taking some measurements, they probably marched less than a mile and a half in total, with a bit of zigzagging built into the route. With some decent coordination between them and their transportation for picking them up, and keeping a decent pace while moving, they likely boosted their odds of being spotted by tourists (who would be taking pictures of what they saw, anyway) while minimizing their odds of reporters or police catching up to them.
