Random space laws.

[Sundance]

My reasoning for implementing it, rather than letting it stay in some vague space of imagination is that with some tangibility, maybe Sec won't get beat to death for having interactions with the crew on shoddy grounds.

And my point about the vague space of imagination is the casual aspect of it. With that, it can be argued, discussed even. A traitor with appropriate wording could probably talk his way out of a jail cell or the lethal injection. If something is written in a tangible form, you'll have people follow that to the letter, and that's a bad thing in my opinion.
Let's take the tomato example (I know it's an example you just thought off the top of your head, but i'mma roll with it anyway).
If a sec arrested me for constantly throwing tomatoes at someone and I asked him why and he gave me a verbose reason as to why, i'd be pretty satisfied. I know some officers often don't often give reason if they arrested on grounds for something minor, but let's say that he did. If he didn't and did the whole silent treatment, i'd suspect him of being a mindslave or someone that isn't used to goon security. That'd make me not trust that one officer.
If sec arrested me on the same grounds but when I asked why and they showed me an official document stating that tomatoes are outlawed my reaction would be to not trust the entire security department and/or react in a manner where i'd be all like "ugh it's the illegal tomato law again"

That's from a civilian perspective. But what of a security perspective? Some officers take their roles super duper seriously and i'm not talking about being trigger happy. I'm talking about using all of the security measures one has access to, from using the headsets to keeping track of fingerprints to discussing appropriate punishments and having "sec meetings" and such. Note that all these measures are aimed against the antagonist. Then you'd have this other officer who's arresting people for tomatoes because the random laws stated as such and that would honestly undermine alot of the work that the super serious officers were trying to do, due to the crew often yelling about shit security, even going as far as to say security are mindslaved.

It's about what this adds to being a security officer. If it's like miscreant where maybe sometimes an officer might follow it, but by choosing to follow it they may undermine security then i'm not sure what it adds.
