The Devils are in a No Win situation here. Damned if they did nothing (and supported their player) and damned (by some) for taking a reasonable reaction. Few, if any know the full facts, but the Devils here have acted correctly IMO.
Players and Staff representing the Devils will have a code of conduct, just like any of us will have in work.
If our actions are perceived to have fallen short of those defined standards, then an appropriate enquiries/investigation should be carried out and determinations should be allowed to fully conclude.
Many previous posts have drawn their conclusions from snippets or postings on Social Media - IMO that's like have 20 pieces to a 100 piece Jigsaw and somehow claiming you have the full picture. I fully expect TK will want to ensure he has all of the available information before deciding what, if any, sanction should follow.
