The discussion of robo-cop in the other thread gave me an idea for a powerful but fairly straightforward piece of science fiction technology that could be added to the game: the v-chip. The arch conservative cousin of the TV modification, this brain implant controls the victims behavoir "for their own safety." The v-chip would be invented and announced in the news once the public support is in favor of the liberal agenda, making the game harder when you're winning, not losing. The v-chip does severely restricts the actions that a liberal is capable of taking, rendering even elite liberals nearly helpless. Anything illegal, violent or rebellious is prevented i.e. combat, recruiting, hacking, disturbing the peace even holding spraypaint and much more. Only completely peaceful actions are allowed like first-aid and seduction.
Whenever a liberal is arrested, they are immediately fitted with a v-chip. For minor crimes, the v-chip will be removed after the liberal stands trial whether found guilty or innocent but if the defendants rap sheet is hot enough, the v-chip stays, even a sleeper judge will have their v-chip removal overruled on appeal. And if you free a liberal from prison before they stand trial, the will automatically be v-chipped. In an arch conservative society, you can free a liberal without them being killed, but in a liberal society, it's almost impossible to escape without being chipped.
The v-chip isn't a life sentence, but it's not easy to escape. After a long time (several years?), a v-chip will break down, freeing the victim. If law enforcement, free speech and the supreme court are L+, v-chips will be banned but by then you've almost won the game. Likewise, if the country starts turning conservative again, the v-chip will become infrequent. Conservatives prefer conservative "justice" to the v-chip so if a liberal is beaten when freed from the lockup or prison then their v-chip was disabled so the cops claim they were "provoked".
