They want to readjust the distribution of resources because they feel the resources are unfairly located. The exploiter, does just that, exploits an issue for his own personal gains. Beyond educating people about the sides of an issues, interest groups are frequently responsible for bringing the issue to light in the first place. Cobb and Elder expalin two types of triggering devices, internal and external. What they mean by triggering devices are the events that set off the issue in the first place.
Internal events are events within the United States.
I tend to agree with the authors that these triggering devices do bring about an issues that the public is usually interested in or has come concerns about and advocate on it behalf. However, I also believe that with the political power behind you, very little can be done to make any type of changes on the issues that concern you. For example, here in Corpus Christi, gang related activities have long been a concern of the public and many interest groups and individuals have publicized this issue. As a result alot of money and time has been allocated to resolving this issue. New laws have been enacted such as the curfew law that restricts minors from being out too late and engaging themselves in gang related activities.
