Resumes are personal advertisements.
People need to know how to present themselves.
I cannot tell you the numbers of times that I have heard from a candidate who sent in a one page resume and upon questioning learned that anywhere from 5 to 15 years were left off the resume!
We've all been told at one time or another to keep our resume to one page, but this old standard no longer holds true. If you have enough experience and accomplishments to highlight on two pages, go for it. Of course, if you're new to the workforce, one page should suffice.
Now that resumes are often entered into an applicant-tracking system, it's more important than ever to include keywords that help the system match you to the appropriate position. You might need more space to do that. This is even more essential for loss prevention professionals who have evolved into more technical or analytical roles. If you are an experienced professional and you need the room to showcase your accomplishments, do not be afraid to go for the extra page or pages.
As to the objective or summary sections at the beginning of the resume, there is a school of thought that suggests going right to your experience. I personally agree with that suggestion. If you have strong skill sets and good accomplishments, they will come out loud and clear in the experience section.
