No neighborhood is 100% safe anymore. You should be out there watching them. Just my two cents. You never know when some piece of shit will come take your kids. Sadly the only safe place for unattended children is a backyard.

Edit. I'm not talking about the whole police thing. In our town a man tried to take 5 kids from diff schools last year and two days ago a man tried to put a 14 girl waiting at soccer practice in his car. I'm just saying its not very safe for kids anymore. I don't get why everyone is jumping on my back.
