this is a very self-centered argument whether the Tam behaved appropriately. This episode is a simple proof that such behavior is not appropriate as it may cause moris ayin and a long prison term.
Maybe, just maybe, there is room to permit when there is a camera that will help during prosecution. Even then it is a big bitul Torah for the Tam, the youngele, his ima, dayan and lawyers, most of whom might be Jewish. And the camera may be off.
To sum, staying away from questionable behavior that might cause a problem is an etzah tova. If you don’t want to walk between two nashim tzadkiyos, just get out a sefer and wait until they finish the conversation. At worse, you’ll do an extra siyum.
