Basically, yes. It's sort of like being guinea pigs.

... it would likely be easier if it's on a Thursday, or if it's really just out in the open. Disguising a death as an accident or a consequence of the setting, like how Ishtar died, wouldn't seem weird.

It's just very specifically the time frame where we have to block them from viewing that's more risky. It just looks weird, if thirty something people are there on Saturday, and then by Sunday they're down four.
