No, Kaslin’s right.
We don’t have any proof.
Now.
All we do have is a whole bunch of....well, curiosities.
JMHO, best thing to do is keep on gathering them up and stick them all in a nice tidy file with an appropriate label (The old english phrase “Too Clever By Half” strikes me as a reasonable choice) until the day that either those accumulated curiosities begin to brew and meld and stink just a bit and “somebody” talks a bit too much and a really bright prosecutor hauls some decrepit old hulk (and equally ancient accomplices) up on long-overdue charges. While we sit and chuckle and share some nice fresh popcorn.
Meantime, we can be patient. Gathering curiosities almost demands it since hurrying could lead to missing something absolutely vital.
Ain’t a Statute of Limitations on stuff like this anyway and I always have been partial to having my revenge or justice served very, very cold.
Had Scalia been a left wing jurist, the identity of his murderer would already be known.
