personally i think the problem is that a majority of street thugs dont have a sense of personal responsibility and would just as soon shoot you in the head and jack $17 out of your pocket as look at you.
this lady's house can be fixed, as can her decision as to what type of person she associates herself with
sorry about your house, but they cops arent just going to go away because of your best attempt at a Jedi mind trick "this is not the house your looking for" or "the bad guy isnt here" yeah... good luck with that. im sure the guy was considered well armed and dangerous and thats why they took the precautions / actions that they did.
