illegal tenants

I live on a short street in islip.  A  house on my street has tenants and 5 cars also 1 more on the weekends.  These people live like cockroaches. 1 car is parked in the driveway that can easily fit 2 cars. All the other cars are on the street taking up everyones parking, why because it is to much trouble to move their   cars around. When people get tired of this and call the town they will cry why ? The IRS will love to talk to about all that extra income you don't claim too.  Plus all the back taxes you don't pay the town. You better wake up and be more understanding to the rest of the neighbor hood or they will be knocking at your door.  You like to make yourself look good but in reality your just mooching off the rest of us and live like cockroaches.
