I would contact the local police department and run your questions past them. Arlington as a whole has changed quite a bit over the years as has most cities in the United States. Simply, it is a more seasoned community with older establised neighborhoods now v. in the 70's it was upcoming. If you would like more information and a more in depth opinion feel free to contact me directly I would love the opportunity to help you find an estate that meets your expectations and doesn't breach you comfort zone; in referrence to your concerns with a safe neighborhood.
