How can i reword this so it could be my conclusion?

By the start of the twenty-first century, gang violence (sometimes referred to as street violence) can be found in nearly all suburban, metropolitan and inner-city communities throughout the United States. One of the main reasons for gang violence is because they are constantly fighting over turfs. This leads to aggressive acts from other gang members who in return defend their territory. In “ Always Running” Luis J. Rodriguez accurately depicts how he faced gangs.
