Note that this mission appears on your map, but you can only start it if you choose to "Corrupt Fetch" at the end of Go Fetch. Your goal in this mission is to go after the anti-Conduit activists, so head to the first location and just start shooting at them until you get the message that they were silenced. Of course, it's likely that the DUP will show up and cause some problems, so start going after them until you get rid of them all.
Fetch mentions that she wants to go after the leader of the activists, but you will need to flush him out first. There will be three rallies marked on your map and you need to go to each one, disrupt the rally and take out the DUP that interfere. Note that you don't need to defeat all of the DUP Agents, but just keep at each spot until it disappears from your map.
Once you clear all three rallies, Fetch will say that she got a fix on the location of the leader of the activists. Head to the tunnel and go inside, where you will find plenty of DUP Agents, including one or two of the stronger ones that can bind your legs. Remember to use the vehicles as cover and don't forget you have two different powers now, so you can switch if you want.
At the end of the tunnel, you will fake surrender and be confronted with a barricade of DUP Agents. Note that you will automatically get a Karmic Streak attack if you didn't have one saved, so when you get the chance, use that to take them all out. Now, a bunch more DUP Agents will come, so continue fighting them until you finish them all off, which will end the mission.
