[Westworld] How do the park operators prevent patrons from stabbing each other?

I get that the guns are fake so the patrons can't get hurt or hurt each other, but the knives seem to be real.  Additionally, the guests don't seem to be able to tell who's a guest and who's a host, so what's to stop them from stabbing a guest they assume to be a host?

There'll be a line in the small print of the disclaimer that they sign when first booking the holiday. It'll say that the company is not responsible for the actions of other guests, guests hurting themselves, guests accidentally falling into a ravine and having their skull crushed by a rock, etc...

Realistically, though, the hosts are also (subconsciously) monitoring what's happening around them, and will no doubt subtly move into a position whereby they can intervene, if at all possible. Teddy, for example, grabbed MIB's knife at the mention of a possible threat.

An earlier person asked why they have over-powerful CPUs; it's because they are most likely multitasking a lot of background stuff like this, as well as "running" their own narrative.

Edit: There's nothing really stopping guests from causing mayhem if they are determined enough and can find an opportunity to do so. But we've already seen that *everything* gets monitored, even when they're asleep or shagging.
