I see at least 2 separate issues in this story: First, regardless of anything else, this woman is to be congratulated for her presence of mind and for not wasting her Marines' and Police training. She did whatever she had to to get away from the shooter -- even to the extent of jumping off a 2nd story balcony! She'd likely be dead had she not done so.
But 2nd, although we cannot know from the article whether she attracted or was herself a lowlife -- the landlord was still justified in evicting her.
Landlords, today, are sued for just about anything. He is responsible if his tenant is assaulted in the hall because he didn't a) secure the hall, b) the light bulb was burned out or missing (probably taken by tenants' kids), c) didn't adequately check the background of tenants -- and on and on unendingly.
So now that the landlord knows that this tenant has attracted gun-fire to his property -- if it happens again, he can be sued for not taking adequate steps to foreclose the possibility.
So if the landlord decided that evicting her was his best move, I certainly don't blame him for doing so.
Don't get mad at the landlord. Get mad at the lawyers who go after anyone with deep pockets or insurance. And get mad at the increasing proportion of citizens who see suing someone as a version of playing the lotto.
