It's Renegade the Grammy Awards dog with the GREEN LEASH!
2 12 2019
9 11 22 2
Makes 9/11 '2' (for them)
Makes 11/22 (JFK assass date)
Extra 2 at the end for Jr (#2) [mirror]
Mirrors 9-11 because (they) experience the pain.
Mirrors 11/22 because instead of life → death, death → life.
I was thinking more 711, 712-ish, but this would better fit the (pic related) 19.5-ish years later theme suggested by 4ch post.
Of course that was 6 days post 11/22…maybe 2/18.
