If Ken Griffin put in GME shorts before ordering his market making desks to quit in it, yes, that would be criminal.
If a fund manager bought puts a few hours before the market makers put up a white flag, I'd want a thorough investigation to rule out collusion. But by itself, suspicious--nothing more. If a long-short value fund bought puts based on an algorithm keyed in months ago before market makers fled the scene, it's almost certainly innocuous.
And if the options desk was hedging the puts they just sold by selling short while the cash equities desk called it quits on the name, that would be perfectly normal.
