I had to to an exercise on summarizing a paragraph. Can I get an opinion and help revising it. Help me to add what I need and delete what I don't to rewrite it. This below is the summarized paragraph

Arizona has become a principal area

where drugs are smuggled into the United States from Mexico, largely because the state is sparsely populated and infrequently patrolled. Smuggling leads to violence and the introduction of dangerous, illegal substances into America and must be monitored better for the safety of US citizens. Poly-drug organizations smuggling drugs into the United States through Arizona are creating a growing problem, and law enforcement needs to step up and block these dangerous ports of entry.

Is this your summary?

Or is it what you are supposed to summarize in your own words?
