I am 26 years old. I got caught shoplifting when I was 16. I was charged with retail theft. I stole a pack of cigartettes. I would like to become a police officer. Do you think I can? Thanks.

Yeah, you could still get hired. That was ten years ago, and not a very serious offense.

You can still get hired.

Based on what you wrote, you could be hired. Whether or not you get hired could depend on how many times you've stolen (even if you weren't caught), when the last time you've stolen anything was, and what the rest of you background consists of. Of course, your qualifications would be taken into account.
