You do if there is no evidence to support your claims.
First of all, it's a suspicion, not a "claim" (and I thought we already went over this) and secondly there is evidence that there was an ongoing dispute between management and disgruntled Union members objecting to "scabs" on the set.
There is enough "evidence" to look at it. There is not enough "evidence" yet to form a conclusion.
My point is that you were too quick to level blame at that girl when it's still not certain how many other fingers were in this fiasco.
She's probably a dippy Liberal but she still deserves due process.
