Make security "age restricted"

[Sundance]

Other servers have a Warden job for this reason.

pffft. haha
The warden on other servers is literally a do-fuck all job. Y'know why? It's because other servers the brig is locked up tighter than a Mormon's chastity belt. You got individual cells, reinforced walls and windows and floor flashers, all facing a beady eye of one dude who just so happens to have all the fucking guns. It's dystopian levels of awful.

Would additional [security-access] riot suppression gear or objects help? If so, what sort?

Security doesn't need any more riot gear. This would be misdiagnosing the problem to the max. There's on average 1-2 officers on the job, who have to deal with an onslaught of problems and someone smashing lights is akin to spilling milk in comparison to the dudes turning medbay and its adjacent hallway into an inferno.
Giving them better tools will only get them so far, because when they want to slap that dude on the wrist who's smashing lights, well, he's just gonna do what he was does best: Smash his way outta security, and fuck off with a segway.

I said it before and i'll say it again: If you want better control over the brig; redesign the brig. Not an arkham asylum but not a hugbox leave-when-you-fucking-feel-like-it jail.
