If space law and procedure are optional for sec on MRP, then why does rule 4 say "Respect space law and standard operating procedures."

I’m not talking about when sec arrests you for 30 seconds too long or anything, but even though it’s been against the rules for sec to strip for non perma, last time I ahelped it I got told following that rule (aka space law) was optional (and by a headmin no less). What’s up with that? If part of rule 4 states “Respect space law and standard operating procedures.” why does everyone BUT sec have to follow it?

Stripping generally isn’t a punishment, they’re searching you for contraband.
If they took all your items and refused to give them back after you were released, then it would be an issue.
