They should edit out the cuss words with silence. I hope they get fined to the max. No love lost for CBS anyway.
Editing out the naughty words, even with silence, would create some cognitive dissonance. The bleeps and blurps and edits will take away from the grave reality of the situation and perhaps suggest that this is just a "TV show". Some may take it so far as to believe it's just a dramatization. It would be nigh impossible to hear all the profanities and believe this was anything but real. And once viewers realize that, it would strengthen national resolve.
If the FCC is stupid enough to fine CBS for this, I and many others will gladly donate money toward the fine.
