Police isn't played because it lacks interesting things to do. Same can be applied to Intel factions; there's not much one can do on a police or Intel faction that's not already doable on a Navy ID.
I have already discussed for quite a bit after the system classifications rework to also change the Intel IDs accordingly so Houses can roleplay their former claims over systems (i.e. BIS should receive Inverness, Kusari has Tohoku law line, LSF should receive Omicron Nu laws, KOI can get Sigmas, etc.)
In regards to the Police factions themselves, buffing the TLAGSNET will have absolutely no effect on how many people play them. I believe that interest will be much more easily gained through the addition, even if restricted, of /nodock to indies as well. That, and the fact that the patch coming soon will bring with it significant Police changes that will act as a side-activity.
Lastly, smugglers as a whole and traders, as has been discussed, need to be teached by the community on how to act. Sure, metagaming and all are bad, but nothing's more infuriating to deal with than smugglers coming to a nearby system and simply logging off until the lawfuls are gone. That and the fact that most proceed to make mountains of complaints the second they're caught has resulted in smuggler - lawful interaction being pretty much nonexistent and just a massive joke for both parties.
