There Goes the Neighborhood...

I've lived on the north-west side of Chicago basically my whole life. When my family first came from Poland, they moved in with my aunt. Then I came along and my parents decided to move a few streets down. We ended up moving to Eddy Street, and it has been my home ever since.
My neighborhood has always been nice and peaceful. There weren't many kids, which was a down-side for me, but my parents loved it here. It kind of felt like the suburbs because everyone knew each other, everyone talked when they took their dog on a walk, and all was well. 
There are these two big apartments at the beginning of my street that have been empty for a very long time. Nobody wanted to buy them because they were closest to the busy street, Addison. Even if people rented, they left soon-after they moved in. I never really knew anyone from the beginning of my street, so I didn't mind those apartments whatsoever. 
About a year ago, we received some unwanted guests in the neighborhood. Along came Alexis and his posse of cousins and friends. These people were Puerto Rican/African American, which I was totally fine with, until they thought they could come in and mess with everybody on the block.
It is unbelievable how obnoxious these kids could be everyday. The oldest was about 16 and the youngest was around 8 years old. Not only did they bother every single person as much as possible, but they brought danger upon the little kids on our street. Towards the end of the block, there are many families with kids under the age of 5, who can no longer go in front of their own house without supervision.
Alexis and his gang started out doing stupid little things that would bother people like ding-dong-ditching and throwing rocks at windows. I guess they thought that wasn't enough so they walked around carrying harmful things like bats. What can you do to an underaged kid that is carrying around what could be used as a weapon? The worst you can do is yell. Apparently for them, yelling wasn't enough to get the message across.
If people from the block got in their way, they were threatened. I still cannot believe they do this shamelessly, but it's all true. These horrible people from the end of the block were causing our whole neighborhood damage and basically stopping us from being able to go out and talk with a friend or fellow neighbor. Nobody thought this was fair, so obviously the police was called. Our wonderful police, however, did NOTHING about the situation. The kids got a "warning"; what is that going to do? Absolutely nothing. They have calmed down a little bit since the school year started, but hopefully they will move away as quickly as possible. Nobody wants little nuisances on the block like Alexis and his friends. If they left, I'm sure my neighborhood would go back to normal and all would be well once again.
