Criminal Minds original cast member Shemar Moore, who left the show in March, seems to have chimed in on the shocking exit of co-star Thomas Gibson, who was dismissed from the show on Friday over alleged violent behavior on set.

In an Intagram video which has since been deleted from Moore’s account but saved and reposted by a Twitter user, Moore appears to be referencing the firing without ever mentioning Gibson by name.

While the two major on-set physical altercations cases leading to Gibson’s firing involved him hitting a writer-producer (Virgil Williams) and an assistant director (Ian Woolf), the bad blood between Gibson and some of his castmates, particularly Shemar Moore, is well known.

In a breach of contract complaint Gibson’s ex-manager Craig Dorfman filed almost two-years ago over unpaid commissions, Dorfman speaks of verbal altercations between Gibson and Moore, with Dorfman claiming that he “talked Gibson out of physically attacking Moore.”

“Lot of birdies chirping out there; the gossip is real,” Moore said in the Instagram video. “I’ll just say this: I believe in karma. Good things happen to good people. Honest people. Hard-working people. Humble people. People who believe in basic goodness. … Treat people how you expect them to treat you. Celebrate yourself and celebrate your blessings — as you should — but just know that you’re not better than anybody.”

Since his dismissal, Gibson has hired attorneys and is considering filing a lawsuit.
