Given my particular style of GM-img when it comes to SR, plater actions and reactions are handled in-party. My number one rule when I started the last campaign was that while you are free to do whatever you want, there will be reprocussions both good and bad, and your reps will reflect it. In my campaign, it was more about life in the Sixth world, not JUST runs. We had a good chunk of game time dealing with the Rigger's bad decision to rough up a couple of KE detectives (who had the contract in my game, set in Toledo) just because they "pissed me (the rigger) off". For a rigger, he should have realized that cop cars, even plainclothes often come with little things called DASH CAMS.
It was interesting when the detectives used the threat of arrest as leverage against the rigger. Once the rest of the group found out, they were pissed. It kind of went down hill from there. They ended up offing the detectives, and accidently an undercover FBI agent in the process....this lead to them hooking up with the local mafia don for protection, having to do certin "favors", getting set up to take a dive by another mafiaso...then becoming indebted to the FBI, who arrested/rolled them to get info on the mafia family...
It was a mess, but a fun mess to play out. Not all runs are about the yen, sometimes they're about survival.
