Liberal crime squad has certainly come a long way. I'd like to see more things to do though. Once you've pressed the big red button 20 times or shot up the police station 10 you are just doing it to maintain your stats, and it takes away from the fun. It'd be more fun if there were a larger variety of thing to do. Maybe you can bust into the evidence vault at the police station. Maybe you can break into fuel storage at the nuclear plant and steal uranium. Maybe you could break into the control room at the radio and tv studios and shut everything down, or maybe even play something different (could work in conjunction with having stolen data. Have video or audio tapes of CEO's or judges commiting crimes that can be used here).
more site actions and possibilities could add a lot, and having multi step ones (steal something here, use it there), could make things pretty interesting. Furthermore, I think really major actions with serious drawbacks should be possible. You should be able to bomb a site, resulting in an instant and extended closed down, but it should be both dangerous AND unpopular. It should still give juice but should result in an immediate loss of LCS popularity and a backslide for the issues associated with that site.
Another major action would be assassination. It would be exactly what it sounds like, you take out one of the politicians from the status screen, be it a supreme court justice, a senator, or the president or vice president. The result would majorly bad though, instant big hit for popularity with the LCS, loss of popularity in all issues, and instant physical retaliation (in the form of unavoidable raids to ALL your safe houses.) It's possible now to clean out the supreme court easily, but this would allow you to do it yourself rather than just influence the background and let it happen naturally. The instant popularity loss would make it hard to abuse. You aren't going to get elite liberals in this way, because you are taking an immediate hit for doing it. You could even make things worse, shooting a conservative in an elite conservative nation is just going to leave you with an elite conservative replacement.
There's lots of ways to expand the game, these are just a few I'd like.
