I've got a story back from when I was a player, playing the hacker. It's been a while so I've forgotten a few of the specifics but it's pretty good.
Anyhow, we're on a job to investigate a series of murdered kids in the Redmond barrens. After tons of legwork, favors, asking questions of the wrong people (the kind who respond in gunfire), it turns out the perpetrator is a upper-management piece of work for Mitsuhama. I won't get into the details of what he was doing but suffice to say it made us motivated to stop him.
We set up surveillance, take shifts, and wait days for a chance to nab him. We finally get our chance and it goes off without a hitch. Skip scene back to the safehouse, we're arguing what to do with him. I had figured that the solution was obvious, kill the slot. The rest of the group hadn't thought that far ahead and now that he was defenseless and bound to a chair they started to lose their nerve. We had been doing some Robinhooding up to this point, doing bad things sure but only to bad people to help good people. Cold blooded murder was something that (besides myself) the group wasn't quite ready for, regardless of what he had done.
In character I lose my cool and take off saying "Do whatever the frag you like!", partly because I felt it made the scene awesome and partly because I wanted to see what they'd do without me (I had much more experience and the group often turned to me for solutions, so sometimes I would opt out of the decision making process. It only felt fair.).
So, after some talk they decide that they just need to get a bit more evidence and then they can go to Lone Star. Some gamma-scopoline and a little time and the face has gotten more info then he wanted to know, but now they can get the videos the sicko made and have him eye and ear recording telling them where to get the trids. They get them and come back, telling the sicko that it's all over for him, that he's going away for a long, long time and he should just cooperate and make it easier on everyone.
Everyone but me goes to the police station, evil NPC in tow. They're smart enough to only bring stun weapons, have their most up to date fake SINs, and I'm still in contact with them via commlink, begrudgingly reminding them about other things to remember so they appear to be good little UCAS citizens.
They turn him and the evidence they aquired in. My GM asks them "So, there are a few open seats. Do you want to stick around or take off?" He was giving them a chance at escape, but they didn't realize it. They decided to wait, they wanted to see sicko get his karmic reward.
So they wait about an hour when sicko, and two very well dressed men walk out from the hallway laughing politely. "Haha, Well the next eighteen holes I won't go so easy on you!" one of them says to the sicko.
Everyone in the group has the same reaction: their jaw drops. They snap a photo of the guys and ask me to try and look them up. I find them. One is a high priced lawyer for Mitsumama, and the man who was joking with the sicko was the LoneStar-Mitsumama liaison.
They talk for another minute then sicko and lawyer walk up to the group (minus me). He looks at them slyly then pulls out his commlink.
"Hello, cleaner? Ah, yes. I'm in desperate need of having my suit cleaned. Yes, a few troublesome... stains... that need to be ... removed." As he says that he turns to each one of them in turn, spending a few seconds looking at each one. They realize he's taking pictures of them with his cybereyes. "I'm ever so busy, you do pickups at home, yes-oh-you don't have my address on file now do you? Hold on just a moment while I forward that to you." The lawyer then pulls out a manilla folder and hands it to the perv. The perv holds it open in a manner that the players can see, clearly wanting them to know it's contents. It's a dossier on THEM, it's all the info Mitsuhama was able to pull on them. He reads off the address of their safehouse right in front of them. "Same fee as always? A rush charge? Very well, that's reasonable. Very good. Goodbye."
It's now they realize what just happened. This guy is getting off scott free and is now contracting a hit on them, right in front of them, in the middle of a Lone Star precinct, surrounded by two dozen cops. And if they try to stop him right then and there, THEY would be the ones the cops throw to the ground, taze, beat, or worse. They effectively can't do anything at the moment.
He puts the commlink away and walks past them with that sly-smug smile. The group is pissed now, they start after him to follow but get stopped at the door. Lone Star has a few "questions" for them.
They each get thrown into separate interrogation rooms and questioned. It's clear from the questioning that they suspect them of creating counterfeit material to blackmail the sicko NPC. And after checking and rechecking everyone's SINs, sure enough two of them come up as fakes.
The GM is feeling somewhat merciful at this point, instead of killing the SINless or due process, the investigaters decide to "teach these bums a lesson" and just beat the two who failed the SIN check until they overflowed to just one or two physical boxes left. The other two were just harassed emotionally and kept being given the chance to "Make this all go away, we know it was those two SINless that put you up to this. Just give us a confession... nothing bad will happen to you, we promise."
Eventually my character comes down to bail them out. Literally. They're car's impounded and the two who failed the SIN check are black and blue, the two that passed have court dates (they know they'll have to ditch the SINs), nearly all the money thats been made running to this point was spent on posting bail and bribes to let the SINless go, the safehouse is no longer safe, we're now on Mitsuhama's radar and not in a good way, and there's a hit out on four out of five team members. Oh, and did I mention that the sicko was going home safe and sound?
Now the team is ready to kill.
