That would be a thrilling mission. Plus - many elderly people are isolated, because everyone they used to know has died.
In my country we have the problem that many old people call the police for no further reason, like "I heard a noise!" or "There are young people hanging around, remove them!". So police has a file on their computer with all the old people who call the police to get some attention - this is the whole mechanism behind all that, they just want someone to talk to. Unfortunately, that is not the job of a policeman. So they look into the file, and if this person has called the police before for "nonsense", this case gets a very low priority.
Problem for the elderly is now: If there´s a real emergency, police won´t arrive quickly enough.
This is a serious problem, but I do not know how to implement this. But speaking about the eldery, I came up with a little rough mission design.
So a little mission design could look like this:
Anaksha has heard that a gang of thugs beats up people in the area between La Madre and San Pietro. So she goes out to look what is going on.
She notices a group of young men standing around in an alley and an elderly woman with a walking frame approaching. Following an intention, she looks out for a firing position and makes herself ready.
Now the plot could twist, depending on where the story occurs:
In a mini adventure Anaksha could approach the scene when the thugs start to molest the woman, hush the gangsters away (with a little help of her trusty .45), making the old woman give her an item she can use (Anaksha would not take money from a poor old lady

).
In a sniper game, Anaksha could observe the scenery through her scope. This could be a tricky one: Maybe the young men do not molest the woman, but help her to carry her groceries to her flat upstairs, so the mission would be a failure if you shoot anyone. (This would be kinda fun to see everyone appear in the forum and whine "I can not solve the mission "X"! Every time I shoot the gangsters, but I fail!"

)
Or it is business as usual - the thugs follow the lady home, she tries to flee, finds an old phone box, Anaksha helps her with one or two rifle rounds. Then she waits for the police to arrive (she does not want to leave the old woman all alone) and leaves the scene.
What do you think about this?
