Missed the point: the neighbors are ignoring the police, and you suffer. Now you are frustrated at the advice "don't talk to the police for any reason". Just an example.
Unless, of course, your neighbors consider themselves potential victims as well, and cooperate based on a sense of self-interest, rather than concern for your well-being.
This would also make sense, and just goes to show how the "never talk to the police for any reason" meme is just plain silly, not to mention antisocial and dickish (if nobody ever talked to the police for any reason, then no criminals would ever get locked up). It's just part of a paranoid mindset which gets you karma on the internet but probably doesn't do you any good in the real world.
By all means have your wits around you when talking to the police, especially if you think they suspect you of something, but the police are not out to get their jollies by locking up innocent folks for no reason, and your chance of winding up in prison for a crime you didn't commit based on a random off-hand innocent remark to a police officer is... much lower than other things you hardly ever think about.
Hey, did you know that you have a one in eight hundred chance of getting multiple sclerosis? Go worry about that for a while instead.
