As for targeting, how about the last person to have mugged or attacked you?

That's a good idea. If you use it right away, they have a chance of completing it. If they're offline by the time you use it, they may not see the mission and end up screwed in some way.

Sadly, as is evident, I did not have time to jump on creating this last week as I'd hoped.

No rush on it to be honest. I'd much rather see well thought out amens dropped every now and then instead of every week anyways to be honest.
