Random thought that could be fun, take a liner, make it a cruiser/transport hybrid (like how frigates are gunboat/transport) make it a dedicated prison ship for police ID's. Now they have a pseudo cruiser option that is flavorful.
The main problem with saying no caps at all is that pirates very much do have capship access, there are very few that dont have at least cruiser, if not even bigger. So this could be an option to have police still be viable to a degree without full cap access.
Also before people say Bustard, that's it's own separate thing, more of a weird liner/battleship/cruiser mix
The thread does raise some interesting points though, police is generally considered 'navy light', OFs get nodock sure but they're rare far between, /net is useful enough but it comes at a pretty decent price of not being able to field heavier assets, which are sometimes needed if you can't field numbers to compensate. (Not counting the random ace pilot here and there that could solo half of the server). If anything it's an amazing support ability, being able to coordinate assets to intercept and block intrusions/smugglers, but that too requires numbers to do with any real efficiency. Lets say you're at Manhattan and you see a smuggler coming in from Texas to Norfolk via /net. You'll still need to guess if they're going to west point or fort bush, guess wrong and they get away with 0 interaction. Should you be 100% guaranteed to intercept them just because you have /net? Of course not. But it does go to show that numbers help considerably.
Giving all police nodock does feel like it'll result in trolling, but with a 3 minute cooldown it might be manageable. Odds are though staff will get more sanction reports of 'nodocks' that were considered unprovoked. Also if memory serves nodock technically doesn't care about where you are, staff will have to correct me on this, but if so someone could in theory go far outside their territory to troll with the command, at which case I can definitely see why it's limited to OFs.
Navy not enforcing laws honestly probably wouldn't influence things as much as people might fear. ID lines of 'able to engage enemy combat vessels' etc etc already cover 90% of their activities. Navies dont mass log to catch a smuggler, they mass log when a pirate group strolls into their turf, the combat lines already cover this, so house laws matter very little. There might be a few awkward situations though, like a junker transport casually strolling through with a cargohold full of artifacts or cardi.
I'll refrain from commenting on Intel ID's, mostly because I'm still thinking about the points raised and my own views on them, but I don't think looking at them is a bad idea, especially in the context of balancing the 'three lawful factors' of each house.
